Introducing the Dormer Pramet A977 12.50 mm HSS-E High Perf Multi-App Straight Shank Extra Long Series Drill (DIN 1869 / 2). This premium drill is built for serious metalworking, delivering precise deep-hole drilling with exceptional reliability in a compact, straight-shank design.

Why this drill stands out

• 130-degree point for confident starts and self-centering performance, reducing the push force needed to begin a bore and minimizing wandering on tougher workpieces.
• Bright finish helps prevent workpiece material from sticking to the cutting edge, promoting cleaner cuts and steadier chip flow.
• Special parabolic flute design engineered for drilling extra deep holes in a single pass, enabling efficient chip evacuation and improved hole quality from top to bottom.
• Premium HSS-E material with enhanced heat resistance and edge life, suitable for a broad range of metals including steel, aluminum, and stainless steel.
• Extra long length series delivers increased reach for deep bores, blind holes, and applications where standard bits fall short without sacrificing rigidity.
• DIN 1869 / 2 compatibility ensures consistent size, fit, and interchangeability with compatible drill chucks and holders for seamless shop-floor use.

This multi-application drill is ideal for machinists, maintenance technicians, and engineers who routinely encounter deep-hole tasks. Use it for tough materials and tight tolerances where one bit should handle a variety of metals, from structural steel to stainless components and die-cast aluminum. The A977 series combines depth, accuracy, and durability in a single, trusted tool.

Practical tips for best results: maintain steady feed pressure and moderate cutting speeds, use appropriate lubrication or coolant for metal drilling, and ensure your drill is properly sharpened and securely clamped to prevent deflection during deep bores.
