M1-RIDGBOR (Super Sharp, Super Hard, Metal Cutting Bell Hanger Bits)
M1-Ridgbor Extension Bits These bits will cut through Metal lath, Nails, Knots, and "Hard Woods" easily. Most bell are made of carbon tool steel, suitable for wood only. The Ridgbor is made of the same M-1 steel used in bits manufactured for production cutting of tough metals. The unique difference between the reduced series M-1 Ridgbor° and other HSS extension bits is the secondary machining process. The Reduced M-1 Ridgbors are machined down, all the way into the bottom of the flute allowing 100% chip clearance and smooth, non-binding penetration. Especially suitable for drilling through both metal and wood (including nail embedded wood). The Ridgbor does not have a wire pull hole.
