Dormer Pramet R457 15.80 mm CARBIDE TIALN FORCE-X STEPPED SHANK COOLANT FEED SHORT SERIES (X3D) DRILL DIN 6537 K

The Dormer Pramet R457 15.80 mm carbide drill is a high‑performance solution for rapid, precise hole making across a range of metals. With a DIN 6537 K shank, a robust 15.80 mm diameter and a TiAlN coating, this drill is built for reliability in demanding shop environments—from engineering prototypes to production runs.

Its 140 degree 4‑facet split point centers itself at startup, reducing the push force needed and helping you hit clean, accurate starts every time. The premium carbide construction and a dedicated flute design with coolant feed work together to support higher speeds and feeds while maintaining edge integrity.

• 140° four‑facet split point: Self‑centering start with reduced pushing effort, delivering clean first holes and fewer wandering starts.
• TiAlN coating for longer life: Extends tool life and improves performance on harder materials, reducing tool changes and downtime.
• Force‑X flute design with coolant feed: Increased strength at higher speeds/feeds and effective heat management for reliable, high‑quality holes.

Designed for versatile metal drilling, the R457 covers steel, aluminum, and stainless steel thanks to premium carbide and coated protection. The hardened shank and short series offer solid grip and control in handheld and machine setups. The coolant feed helps manage heat during aggressive cutting, minimizing built‑up edge and improving hole quality, with h9 tolerance delivering precise hole sizes for critical fits. For shops aiming to reduce tool changes and maintain throughput, this drill consistently delivers repeatable, high‑quality results across demanding applications.
