## Description

KEENTECH 3/8" x 1/8" Carbide Tipped Countersink Drill Bit with Depth Stop | 1/4" Shank, 82°, Adjustable Depth Stop with Ball Bearing for High Fine Finish on Softwood and Hardwood - desertcart.com

Review: A great value that does what it should do - I used this on MDF that I needed to blend with some trim around a fireplace. This is a great option and value: it did the job well. The holes were perfectly smooth and there were no marks from the depth stop. Definitely try on a piece of scrap material first to check your depth, etc. My opinion I that unless you’re doing some fine woodworking, or your holes (which you will likely attempt to cover) are highly likely to be visible in your end product, there’s no reason to look beyond this bit. The bearings aren’t quite as smooth as shown in the product video (spinning the depth stop doesn’t carry any momentum really), but do work well enough for their purpose. I found the depth measurement a little confusing, but trial and error on a piece of scrap solves that. Non-negative numbers are marked but seem to increase as you reduce depth, so I’m not sure what they mean. Also, the pilot bit depth is not adjustable, so you cannot easily use this to pilot through an outer piece and the piece it will be screwed to; you will probably have to make your countersink holes and then follow up with an equally sized bit through that into your underlying piece, etc. This is my first countersink bit, so I don’t know if that’s common, but I thought I saw some with adjustable and/or replaceable pilot bits. I have no regrets that I didn’t drop substantially more cash on a bit I’ll likely use only sparingly.
Review: Updates review from 2 stars to 5. Please read - I was excited to get and use this bit. Unfortunately the drill bit was next to impossible to adjust and the set screw ended up getting stuck and rendering the bit useless and unusable. *Review update* I changed my review from 2 stars to 5 based on a few things. First of all Keentech independently reached out to me to offer a full refund. I instead asked for a replacement, which was sent out and I received 2 days later. I then used the product again and it was clear the first bit I got was defective. The new bit works brilliantly and the depth stop is amazing. I’m sincerely happy I got a working bit as I was excited to try it the first go around. Outstanding customer service and a great product when not defective.

### ⭐⭐⭐⭐ countersink bit
*by E***A on January 29, 2026*

The KEENTECH 82° carbide‑tipped countersink is a solid performer that lives up to its reputation. The 3/8‑inch outer diameter and 1/8‑inch pilot drill give a clean, precise entry, while the carbide tip stays sharp even after repeated use on stainless steel and aluminum. What sets it apart is the built‑in depth stop – it clicks into place and guarantees consistent countersink depth every time, eliminating guesswork and saving setup time. The bit feels robust, fits snugly in a standard chuck, and delivers a smooth, burr‑free finish that makes it a must‑have for any workshop.
