KYOCERA SGS - 54621 - 3/8" (.3750") 3 Flute Carbide 3xD Stub Length Drill, 10mm Shank, 1.8504" Flute, 3.5039" OAL, 124° Point. SGS Hi-PerCarb Series 131N, Bright Finish Uncoated For Aluminum & Non-Ferrous

KYOCERA SGS - 3/8" (.3750") 3 Flute Carbide 3xD Stub Length Drill, 10mm Shank, 1.8504" Flute, 3.5039" OAL, 124° Point. SGS Hi-PerCarb Series 131N, Bright Finish Uncoated For Aluminum & Non-Ferrous

SGS Hi-Percarb® Series 131N - High Performance Carbide Drills For Aluminum. The Key Features Designed Into The Hi-Percarb® Series 131N Drill Allow The Product To Offer Application Benefits Not Only Beyond That Of Standard Carbide Drills, But Also Other High Performance Drills. Each Feature Of The Hi-Percarb® Series 131N Drill Was Uniquely Engineered As A Solution Towards Addressing The Issues Commonly Encountered During High Production Drilling. The 3-Margin Design Provides Improved Hole Stability Over Two-Flute Designs With Superior Surface Finish, Roundness And Hole Cylindricity For Unsurpassed Hole Size Control. The Self-Stabilizing Pyramid Point Design Stabilizes The Drill On Contact With The Workpiece And The Open Flute Structure Efficiently Transports Chips While Maintaining Strength At High Feed Rates. The Sculpted Gash Allows Chips To Easily Flow Away From The Drill Center For Reduced Cutting Forces Over Competitive Three-Flute Designs. The Minimal Margin Design Reduces Frictional Heat Generated By Excessive Margin Contact With The Workpiece While The Parallel Design Maintains Contact Width As The Drill Margin Wears, For Ultimate Performance Consistency. The Sgs Hi-Percarb® Series 131N Drills Are Offered Uncoated With A Bright Finish Or With Ti-Namite-B (Tib2) High Performance Coating. This Ceramic Based Coating Ensures A Smooth Surface And A Low AfNity To Cold Welding Or Edge Build-Up, Which Makes It Optimal For Aluminum And Copper Applications. It Has High Toughness And High Hardness.
