Annular Cutters ANNULAR CUTTERS Achieve burr-free finished holes, without predrilling or stepdrilling Precision-ground flutes provide efficient chip clearance, increasing drilling productivity and decreasing cutter breakage Hardened, high-speed tool steel Weldon Shank Benefits of CS Unitec's Cutter Design: Double-action tooth geometry cuts, splits and ejects chips more efficiently, • increasing cutting speed • reducing tooth load • minimizing tool wear • lengthening cutter life Engineered with a tapered inner wall for smooth, easy slug ejection. Center hole for pilot pin accurately aligns the cutter, allows for internal lubrication and removes the slug. Perfect drilling to close tolerances without runout. The result: a burr-free finished hole. 32 • 1-800-700-5919 • Visit our Web site at www.csunitec.com

Pilot Pins: How they work… 2: Oiling 3: Ejecting During drilling, the pilot pin retracts and allows internal coolant to reach the cutting teeth. When hole is complete, the slug is automatically ejected from the cutter. ANNULAR CUTTERS 1: Centering The pilot pin accurately centers cutter over area to be drilled. 6-Series HSS Unibroach™ Annular Cutters – Pages 34-35 Fully ground HSS annular cutters Cutting depth: 1" 2" Drilling ø: 7/16" - 5-1/8" 7/16" - 5-1/8" 3" 3/4" - 5-1/8" 4" 3/4" - 5-1/8" 8-Series ARMOR-PLATED Unibroach™ Annular Cutters – Pages 36-37 Fully ground HSS annular cutters with...
