FEATURES: • Right hand (clockwise rotation) cutting direction. • Standard two flute design. • Standard spiral, helical flutes. • All drills have reduced shanks that are 1/2" in diameter. • Some TTC Production sizes may be supplied in 135° drill point. TECHNICAL DATA: • Manufactured from cobalt steel. • Surface treated. • Black and bright finishes. TTC Production • 118° point angle and standard web thickness. Precision • 118° split point and are self-centering. Silver & Deming Drill Sets Page 95 NOTE: • Special care should be exercised to avoid bending or shearing the reduced diameter drill shank.
