Drill America KFDRSD series Killer Force Drill reduced shank drill bit. It is manufactured from premium grade High-Speed Steel, has a heavy-duty 135 split point and is identical to silver and deming drills in both 6-inches overall length (OAL) and in length of cut 3-inches (LOC). Black and gold surface-treatment reduces friction and facilitates effective use of lubricants. Reduced 3-flat shank ensures a secure grip in jawed-chucks. Precision ground for high degree of concentricity between shank and body diameter. Ideal for drilling in low and medium tensile strength materials.
- High-speed steel tools are good for most general purpose applications, offering a combination of hardness and toughness for wear resistance
- Gold and black surface treated for use in stainless steel and other hard metal drilling
- 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
- Heavy duty 135 degree split point
