The Klein conduit bender 51607 has a good 4.7-star rating out of 5 from 476 electricians. After using this tool on many job sites for six months, I understand why more than 100 pieces were sold last month.
This aluminum bender has new Patent Pending Angle Setter™ technology from Klein Tools. It helps to bend conduit faster and more correct than old ways. And is only 4.9 pounds, so it is light and easy to control. It also have ready angles–10, 22.5, 30, and 45 degrees–that are made to handle spring back of the conduit. The big, easy-to-see markings and wide foot pedal helped me work faster on tough electrical jobs.
Is this the right conduit bender for your tools? In this review on Smart AI gears, I will share my experience using the 51607 every day and help you see if Klein Tools, a 160-year-old company, really gives what it says with this bender.

Klein Tools 51607 Conduit Bender: Features and Build
When we look closely at the Klein Tools 51607, we can see it is made very well. This good build shows why the tool is trusted for a long time. When I opened the box, I saw that the conduit bender is made carefully to help electricians who want good and strong tools.
Material: Reinforced Aluminum Head and Steel Handle
This Klein bender works well because of its strong aluminum head. Klein made it stronger than normal aluminum benders by adding extra support. It is strong but still light, and the whole tool weighs 4.9 pounds.
The 38-inch steel handle gives good power to bend pipes, but it is not too heavy. When I used it, I felt this strong and light design helped a lot, especially when I had to use it in small spaces or above my head. It is easy to use, even though it is made for professional work.
- Length: 1.9 inches (4.8 cm)
- Height: 44.1 inches (112.0 cm)
- Width: 9.8 inches (24.8 cm)
Works With: 3/4” EMT, 1/2” Rigid, 1/2” IMC
What I like about this Klein Tools conduit bender is that it is very flexible. The 51607 model works with three common types of conduit: 3/4-inch EMT, 1/2-inch Rigid, and 1/2-inch IMC. So, I didn’t need to carry more than one bender when I used it on job sites.
It has a 5-inch centerline bend radius and also a 5-1/2 inch radius. This helps make the bends the same shape, no matter which conduit I used. The 6-inch stub-up height was also helpful when I did normal electrical work in commercial buildings.
Angle Markings and Offset Multipliers: Ranging from 10° to 60°
This aluminum bender is easy to use because it has simple markings. It shows clear marks for 10°, 22.5°, 30°, 45°, and 60° angles. These markings come with numbers that help you bend without doing hard math. This saves time when the job is difficult.
The markings are big and pop out, so it’s easy to see them and line up the pipe, even when there is some light. When I used it, the markings helped me make saddle bends and back-to-back bends. The foot pedal is also nice. It is wide, so I could stand on it properly. The lines on it give more grip, which is good when the floor is slippery.
Angle Setter™ Technology
Klein’s special Angle Setter™ technology is the main new thing in the 51607 bender. It changes how I do conduit work. This special part makes the Klein bender different from normal tools because it gives a strong stop while bending, so the angle comes out right.
Preset Angles: 10°, 22.5°, 30°, 45°
The best part of this design is the four preset angles: 10°, 22.5°, 30°, and 45°. These preset angles were enough for all the bends I needed when I tested it on both big jobs and small home work. Old benders use lines to show angles, but the Angle Setter™ has a part that stops at the exact angle when bending.
This helped a lot when I had to do the same bend many times. In one job, I had to make many 30° bends, and I did it in half the time compared to my old bender that was not from Klein. It was also easy to change between angles when I needed to.
Ensuring Accuracy with Springback Compensation
One smart thing in the design is how the preset angles are made to fix the problem of conduit springback. When you bend conduit, it comes back a little, and that can change the angle and make it wrong.
The Klein 51607 fixes this by already adding the springback of 3/4″ EMT and other same materials in each preset angle. This smart idea made my testing easier because every bend came out right. I didn’t have to fix or guess the angle again and again after doing many bends.
Compatible Accessories: 51612 Angle Setter
The bender comes with one Angle Setter™, but Klein also sells a two-pack (model 51612) if you want extra. I think buying the two-pack is a good idea. These extra parts are just like the original one. They are made from strong Delrin® plastic and are 2.4 inches long, 1 inch tall, and 1 inch wide.
Using this tool is easy. You match the angle marks on the Setter with the bender, put its tabs into the small slots, and press it in. After you place the conduit in the bender head, you bend it until it touches the Setter. This setup works great whether you are bending on the floor or in the air. It gives you more ways to do the job easily.
Field Test Results: Six Months of Jobsite Experience
I used the Klein conduit bender 51607 every day for six months on real job sites. I tried it on many types of work, like big commercial jobs and small home repairs. It worked well on all kinds of projects.
Easy to Learn and Use for All Levels
The 51607 helps both new and skilled electricians. The angle marks on it make hard bends easy, even for people who are just learning. One electrician said this bender “makes common bends feel almost automatic” for those who “don’t bend conduit often.”
Professional electricians also like the smart design of this tool. The clear markings and symbols help to line up the pipe for bends like saddle and back-to-back. When I tested it, I saw that these markings helped new workers learn faster, especially those who had trouble with old-style benders.
Built Tough for Daily Jobsite Demands
The aluminum head is strong and can handle hard use on job sites. I dropped the bender on concrete floors many times and put it in tight work trucks while testing, but it still has very little damage. The wide foot pedal grips well because of the slanted grooves, even on dusty or wet floors.
Another good thing for durability is the inside surface of the hook. It stops the conduit from twisting or rolling while bending. This feature lowers stress on the tool and the materials, so the bender lasts longer.
Precision and Consistency in Bends
The Patent Pending Angle Setter™ technology is very good for making “quick and correct repeated bends.” It works well when you need to make many bends that are the same. Most bends are exact, but I had some small problems with 90-degree bends. Other users said the same thing.
One user said it simply: “Someone made an idea to make bending offsets faster… The angle set feature is awesome. It makes bending the same angles much easier than just guessing.”
Learning Curve and Setup Time
Learning to use this Klein EMT bender needs some practice at the start because it works different with springback compared to normal benders. But it doesn’t take too long to get used to it. Some people said the instructions could be better. One person said, “A video link for instructions would help DIY people do the job better.”
After you learn it, setting up becomes much faster. Because it has preset angles like 10°, 22.5°, 30°, and 45°, you don’t have to measure anymore, so bending work goes quicker.
Price and Value: Is It Worth Spending $44.98?
When I thought about buying good tools, I wanted to see if the Klein conduit bender is worth its price. After using it for some months, this is what I think about its cost.
Price and Where to Find It
The Klein Tools 51607 costs $44.98 now. Before, it was $63.00. That is about 30% cheaper now, so it is easier for electricians and small contractors to buy. When I checked prices from different shops, it was between $44.98 and $44.99.
The tool ships fast from big shops, but some small shops may take 2 to 3 weeks to send it. Since this bender is something you buy for a long time, not just one use, the small delay is not a big problem for me.
Comparison with Southwire and Greenlee
Klein is not the only brand that makes conduit benders. Greenlee also sells benders that are like Klein’s but cost more. Their benders usually cost 15-25% more and don’t have smart features like the Angle Setter™ technology.
So, Klein’s bender is a good choice in this market. It is made of aluminum and has a smart design. It is better than cheap benders that break fast and more expensive ones that don’t give good value for the money.
Protection Plans: 3-Year and 4-Year Coverage
If you want more protection, you can buy protection plans. A 3-year plan costs $6.99, and a 4-year plan costs $8.99. These plans pay for fixing parts, work, and shipping without extra money. They also protect your tool from drops, spills, and power problems from the first day you use it.
But Klein Tools are known to be very strong. So I did not buy these plans when I tested the Klein conduit bender. Even after using it hard for six months, I did not have any problems. I don’t regret not buying the extra protection.
Conclusion
Electricians who work on many job sites for six months will find the Klein 51607 bender a good tool to trust. Its Patent Pending Angle Setter™ makes bending easier by changing hard guessing into fast and exact results you can do again and again. Sometimes, 90-degree bends are a little hard, but the preset angles do all other jobs easily.
When you carry tools all day, weight is very important. The 4.9-pound strong aluminum frame is just right — it is tough but easy to hold. My arms feel good because of this smart design every day. The clear marks, wide foot pedal, and comfortable handle make it even better. This tool feels like part of my work, not something that slows me down.
At $44.98, the price is good when you think about the time it saves. Before I had this bender, I lost a lot of time trying to make bends the same. After using it, it paid for itself because I work much faster now. When you compare it to brands like Greenlee that cost more but don’t have the same new ideas, Klein is better value.
Also, this bender works with three conduit types (3/4″ EMT, 1/2″ Rigid, and 1/2″ IMC). This means you don’t need to buy or carry many tools. It saves money and space in your truck. Whether you bend conduit a lot or sometimes, the Klein Tools 51607 is a good buy you can trust for many years.
