Blitz Bits® - Screw Machine Length

Premium High-Speed Steel

Heavy Duty 135 O Split Point Black Oxide & Gold Finish

• Heavy duty construction and shorter length are good for stationary and portable drilling • Shorter flute and overall length increases the rigidity resulting in less deflection, better hole accuracy and longer tool life • The buttressed cutting edge, with an acute rake, makes the BLITZ BIT ® cut cleanly and accurately with less effort The extra clearance behind the side margin reduces friction, enabling balanced cutting action with closer hole tolerances, at higher speeds
