CTD Metric Magnum Super Premium 5mm Drill Bit (2 Pack)

Bought for an electronics project and needed a good 5mm bit to drill in metal and plastic. Worked so well I bought the 10mm as well. Calipers were spot on for size and had a perfect fit for components.

nice twist drill mm bit. very satisfied

Perfect for work. I go through a lot because of my line of work, and I keep ordering these because they’re perfect for my drill.

I bought these because I needed clean holes on both sides of cabinet doors for high end hardware . I recently bought a $300 jig to drill for pulls and the same bit was included.

Had to enlarge bore of a hub by1mm to accommodate a small motor shaft. Wasn't sure it would work out but did the trick!

I used these for drilling cold rolled plates of 316L stainless steel, and they work very well. 316L can be hard to work with, but these bits cut through it easily and they are easy to use to make precise holes and don't wander around.

Have had a chance to use them but once and they worked as expected. Delivery time was great. Could not find the bits locally. Being able to get them on line was a plus.

Cuts like butter. :) Enough said
