Spiral point design has a left hand flute at the point, which provides a positive rake and drives the chip ahead of the tap
Shorter overall thread length minimizes drag after the first full thread
Reduced neck provides clearance to prevent breakage and allows room for lubrication to reach cutting edge
Precision-ground thread design performs better in controlled machine set-ups and tougher off-hand maintenance applications
Three flutes stabilize starting direction, which facilitates tapping straight holes
Manufactured from high-speed steel
Recommended for through holes in most materials
Designed for tapping on machining centers
NOTE: Item No. 61106 through 61111 do not have reduced neck or threads.
