Make it Snappy Tools 5 x 40 Confirmat Countersink #43540

Good quality as described and worked great to pre drill our many DIY projects.

I bought this along with cabinet connector screws to build a melamine cabinet. The drill bit worked well through most of the build until one time when I was backing the bit out it dislodged from their "holder." I found out later that all I had to do was slip it back in and it didn't happen again. I am assuming it was operated error rather than part error. I would recommend this to others.

Excelent quality !!!

Are used this drill bit to countersink Confirmat screws in white melamine drawers. Unfortunately, it started burning the MDF and did not work well after about 15 or 20 drawers with 16 screw holes per drawer. So I had to order another one. I wish it were a bit more durable. Other than durability, this drillbit really does a good job drilling the precise counter sink hole for the CONFIRMAT screws.

Llevo usándolo para una instalación algo grande, he hecho cerca de 1000 barrenos con el antes de sentir que el avellanador perdió filo. Lo recomiendo? Si. Qué consideraría adicional a la compra?, para mayor rendimiento, sugiero usar una broca distinta, la que trae es de calidad decente ( 7/10) pero con otra broca tendría mejor desempeño, y obvio estaría mejor que el avellanador tuviera algún tipo de inserto de carburo de tugsteno para prolongar la vida útil. En general, cubre su objetivo a un precio razonable.
