As a home handyman and inventor, you occasionally have the need to enlarge holes to match other components. Well, we bring good news to you.
With our Construction Reamer Set, you'll be able to easy and efficient to enlarge holes.
- Long service life - The material is high speed steel which is the most common material for this type of tooling
- Suitable for a variety of materials - It works great on sheet metal but will also work on plastics and other metals
- High efficiency - Available use with portable electric and pneumatic tools
- Five-flute, more smooth chip removal
- Spiral tapered reamer, enlarging the holes in the steering knuckles and pitman arm
- The three flats on the shaft, which allow the drill chuck to hold the reamer securely under high torque without slipping
- This is for working on existing holes only
- Tips: Before using construction reamer, please put some cutting oil

The reamers did not hold up. One vents and the other ones got dull.

This is a nice set for the price. Some things good and some minor problems.Plusses:* Sizing all meets the specs (using a caliper).* 5 flute design to prolong life, keep the reamer centered, and provide a smooth finish.Minor Issues:* Some surface rust on shanks. Should have oiled or coated these.* The case is actually ok but the packing insert is a joke. It's soft foam with glued layers and all the glue failed. So, the bits just king of float in the case. Everything was packaged and shipped well. The problems is definitely the design of the foam insert and it unfortunately really takes away from the perceived value of this set.* I'd probably only use these for mild steel or less harder materials. So, like A36 steel would probably be the hardest thing I'd work with these bits without expecting to wear them out super quickly. I didn't try it but I don't see them working will with the very popular A572 (50 ksi) steel that is widely used today.* The machining of the flutes isn't super fine. You can see the machining pattern very easily and it's pretty coarse. You can actually see it in the listing pictures too. My presumption is this is an artifact from minimizing machining passes.Overall, it's hard to see these as for production / professional use. Probably more for occasional and one-off use.

I've found these tapered reamers to be very accurate which is not all that important to me since I'm using nominal sized hardware which are undersized anyways, so hardware fits about the same at if I was using a regular twist bit. However, I have come across a fantastic use in my shop. I like to use stepped bits to enlarge holes from a 3/16" pilot to whatever larger size I need. Step bits are fast, but they leave a tapered hole. I've found that these reamers are just the right size to remove the taper and leave a nicely finished hole. This works really well with thicker material, say 1/4" and up. Just make sure you go super slow and use lots of fluid. I use mostly mild steel like 1018 for my shop projects. Just fyi, these are not like typical chucking reamers which come in plus and minus sizes to achieve different fits, like a press fit and sliding fit, so just because you're using a reamer, don't expect nominal sized hardware to fit any better.
