I had some brad point wood drill bits that were not drilling a decent hole which I was about to replace. The I remembered everyone’s advice about getting the best tools you can (within budget restraints) if you want and expect quality and long lasting performance.
Well after looking and reading for some time about different bit manufacturers and user’s reports on their performance, I decided to purchase a 7 piece set of Colts for about $18.00.
My God was I blown away by their performance, it was like night and day, and would not hesitate to any other woodworking to invest in Colt Twinland Brad Points Bits.
” Description from Colt
1. Exclusive TwinLand design improves accuracy and eliminates burning
2. Second land provides improved guidance when hand drilling
3. Second land seals flutes to prevent chip squeezing and burning
4. Unique brad point design produces cleaner holes while ensuring pin point accuracy in wood
5. Roll-forged flutes and diamond ground tips for sharper, longer life.
At first glance Colt “Twinland” bits may appear to be a 4 fluted, however, a closer look shows that the bits have a slight relief milled in the land (flat area between the flutes) to create 4 lands rather than 2. The extra lands improve guidance when drilling by hand, and help seal the flutes to prevent chip squeezing and burning. The flutes are milled at a 25 degree angle, which vastly improves chip ejection and helps reduce friction and burning. The flutes are roll forged and the cutting tips have been diamond ground to stay sharper and last longer longer. Ideal for boring holes in softwoods, hardwoods, exotic woods, veneers, and laminated wood. Bits under 3/4” have 3/8” or smaller shanks. Bits over 3/4” have 1/2” shanks. Made from alloy steel. Germany.”
I cannot add any more than the manufacturer’s description, I can however assure you that these bits are super. They will not disappoint you.
