Dormer Pramet R520 9.80 mm CARBIDE TiN CDX STRAIGHT SHANK STUB DRILL DIN 6539

The Dormer Pramet R520 9.80 mm carbide stub drill is a versatile tool built for reliable, precise hole making across common metals. With a straight CDX shank and DIN 6539 standard, it fits easily into standard chucks and toolholders for quick, dependable setup. The 130° point helps self-center the start of the hole and reduces the push force required, delivering cleaner starts with less wandering.

Coated with Titanium Nitride (TiN), this drill delivers longer service life and steadier performance when drilling harder materials. Convex cutting edges improve chip control and allow higher cutting speeds and feeds, helping you achieve faster production without sacrificing hole quality. Crafted from premium carbide, it is designed to handle steel, aluminium, and stainless steel with consistent results, maintaining a tight h8 hole tolerance even at high speeds.
