Drillco 450T Series 29 Piece High-Speed Steel Jobber Drill Bit Set, Uncoated (Bright) Finish with TiN Tip, Round Shank, Spiral Flute, 135 Degrees Split Point, 1/16" - 1/2" in 1/64" increments

Drillco 29 piece jobber drill set. TiN coating is applied to the "working" part of the drill. This allows for all of the benefits that the user receives from a fully TiN coated product, but at a reduced price when compared to a drill that is fully coated. The TiN (Titanium Nitrite) coating provides a super hard surface with high lubricity and longer tool life, as the heat is deflected away from the drill. These drills can be used in a wide range of materials including steel, stainless steel, titanium, nickel and aluminum. High-speed steel tools are good for most general purpose applications, offering a combination of hardness and toughness for wear resistance. Titanium nitride coatings add a hard layer of gold-colored ceramic to the surface that extends tool life and permits faster cutting speeds than uncoated tools. Round shanks allow use with a wide variety of toolholding systems. When run in a counterclockwise direction (right-hand cut) spiral fluted tools evacuate chips up and out of the cut to reduce clogging.What's in the Box? 29 jobber length drill bits ranging in size from 1/16" to 1/2" in 1/64" increments
