6.50mm Dia, 136 Degree Point, Solid Carbide Drill - 69258
SERIES: 143
Hi-PerCarb 143M-S
6.50mm Dia, 136 Degree Point, 8.00mm Shank Dia, 91.00mm OAL, 2 Flute, 5xD, Coolant-Through, Ti-NAMITE-A (AlTiN) Coated, Series 143, Hi-PerCarb 143M-S, Solid Carbide Drill - 69258
Feature & Benefits
Coolant through design improves coolant flow to extend tool life and aid in chip evacuation
Eccentric 2-margin design reduces frictional heat and minimizes material adhesion to the margins without weakening the drill
Computer controlled edge honing protects against chip damage
High-performance point design stabilizes on contact for exceptional hole size and cylindricity allowing for low thrust force and extended tool life
SGS Ti-NAMITE®-A coating provides exceptional wear and erosion resistance when drilling heat resisting alloys like Inconel, Stainless Steel, and Titanium Alloys
Recommended for materials ≤ 50HRc (475 Bhn)
