ø15.00 mm 8D Solid Carbide
Coolant-Thru Drill
The 8D ratio tackles deep-hole applications where chip evacuation and heat build-up are the primary failure modes. Internal coolant channels maintain cutting temperature and flush chips continuously, enabling consistent hole quality in steel, stainless, and ductile iron at depths where standard drills fail.
