Dormer Pramet R463 1/8 Inch CARBIDE TIALN FORCE-M STEPPED SHANK COOLANT FEED LONG SERIES (X5D) DRILL DIN 6537 L

The Dormer Pramet R463 1/8 Inch Carbide Drill with TiAlN coating is built for demanding materials like stainless steel and other heat-resistant alloys. Its 140° four-facet split point helps the drill self-center, delivering clean starts with less push force and reducing wandering during initial contact.

Designed with a long-series DIN 6537 L shank, this drill pairs premium carbide with a TiAlN coating to maximize wear resistance and tool life. The ctw flute design with coolant feed supports higher cutting speeds and feeds, improving productivity and hole quality in tough materials.

• Self-centering 140° four-facet split point: Starts holes accurately with less push force, reduces wandering, and improves first-pass hole quality.
• TiAlN coating for extended tool life: Provides enhanced wear resistance on stainless steel and heat-resistant alloys, helping the drill stay sharp longer and reduce tool changes.
• ctw flute design with coolant feed: Improves strength and enables higher cutting speeds and feeds, while efficient coolant flow aids chip evacuation for cleaner holes and better surface finish.

This combination of precision geometry, durable coating, and optimized coolant and flute design translates into consistent, accurate holes with fewer interruptions. The R463 delivers reliable performance in tough materials, supports faster setup and production, and helps you achieve precise hole tolerances (h9) without sacrificing durability or speed.
