Description of Cle Line C69384 Finish 135 Degree 29 Piece
Heavy-duty high-speed drills for drilling in a wide reange of operating conditions and materials. Black & Gold Oxide surface treatment increases wear resistance and adds lubricity to improve chip flow. 135 degree split point. Split point is self centering and excellent for hand help and machince applications. Sizes 3/16 in. and above have a flatted chank for more secure work holding.
As my tests showed these bits were not nearly as effective as advertised. While the finish was decent, the 135 degree angle did not make a significant difference in performance. The price point is also quite high for what you're getting. Save your money and look for another option in the industrial drill bit market. .
Pros
Efficient 135 degree design for better accessibility and reach
Cons
Limited number of pieces included in the set compared to other options on the market
