Champion 113T-C HSS 135 Degree TiN Coated 13pc 700T Drill Set

700T Titanium Nitride Coated Jobber Drills Features and Benefits of TiN Coating: Increased Surface Hardness – TiN coating has a surface hardness in excess of 80 Rockwell, which protects the cutting edge from abrasion and provides a protective shield against the damaging effects of heat generated at the cutting edge. Increased Durability – TiN coating prolongs the sharpness and durability of a tool, allowing it to be run at substantially higher speeds and feeds without the usual problems of breakage and chipping. High Lubricity – The lubricious finish of titanium nitride provides free chip flow, reduced heat buildup and chip welding, creating a superior work piece finish Ability to be Resharpened – Since the TiN coating remains on the interface of the flutes right to the cutting edge, resharpened tools still outperform similar but uncoated HSS tools two to one. Specifications: 1/16 thru 1/4 x 64ths Straight Shank 135 degree Split Point HSS
