The Dormer Pramet A976 6.50 mm HSS-E High-Performance Multi-Application Straight Shank Drill is engineered for precision, reach, and versatility in a single, reliable tool. Designed to tackle a variety of materials with one drill, it’s the go-to solution when you need consistent holes in steel, aluminum, and stainless steel without swapping bits.

Key features that impact every hole you drill

• 130-degree point for self-centering — minimizes wandering and reduces push force, helping you start holes cleanly and maintain accuracy from the first cut.
• Bright finish — a non-stick cutting edge that helps prevent workpiece material from sticking to the edge, especially on harder metals and alloys.
• Parabolic flute design — optimized to evacuate chips efficiently, allowing for drilling very deep holes in a single pass with less clogging and smoother holes.
• Premium HSS-E material — high-speed steel with enhanced toughness and heat resistance, suitable for drilling a wide range of metals including steel, aluminum, and stainless steel.
• Extra-long length series — built for when depth and reach matter, ideal for drilling deep holes, blind-through holes, or recessed work where standard-length drills fall short.
• Strict DIN 1869 / 1 compliance — precision-ground geometry and quality control ensure consistent hole size and concentricity across demanding applications.

The A976 drill isn’t just about making holes—it’s about making the right holes, in the right places, with fewer insertions and less downtime. The combination of a 6.50 mm diameter, a focused 130-degree drill point, and an extra-long straight shank gives you predictable starts, improved rigidity, and outstanding hole quality in challenging setups.

Why this drill stands out in real-world use

• Deep-hole capability with the parabolic flute reduces the frequency of repositions or pecking cycles, helping you complete long runs with fewer interruptions.
• Multi-material flexibility means machinists, fabricators, and tool crammers can rely on a single drill for multiple job types, reducing tool inventory and changeover time.
• Surface-friendly performance with the bright finish translates to cleaner cuts on finish-sensitive components, from automotive housings to precision machined parts.

Ideal use cases

• Deep pocket drilling in steel, stainless steel, and aluminum components where reach is critical.
• Rigid setups for molds, dies, and fixtures requiring precise, concentric holes without tool changes.
• Maintenance and fabrication environments where drilling multiple materials with one drill reduces downtime and preserves workflow.

Practical tips for optimal results

• Secure the workpiece firmly and align the drill with a stable, rigid setup to maximize self-centering benefits.
• Use appropriate coolant or cutting fluid to manage heat, especially in stainless steel and high-strength alloys.
• For very deep holes, consider slight pecking to break chips and maintain effective flute clearance without overfeeding.
• Match feed rate to material hardness and drill diameter to maintain a clean hole and extend tool life.
