Introducing the Dormer Pramet A976 8.50 mm HSS-E High Performance Multi-App Straight Shank Extra Long Drill (DIN 1869/1). Engineered for demanding applications, this drill blends precise geometry with durable materials to deliver consistent holes in a wide range of materials—from steel and stainless to aluminum and beyond.

Key features that matter in the real world

• 130-degree point for self-centering accuracy and reduced push force, meaning smoother starts and cleaner hole entry even in tough or gumming materials.
• Bright finish that resists gumming and prevents workpiece material from sticking to the cutting edge, helping you maintain a clean, sharp bite wholescale in every pass.
• Special parabolic flute design tailored for extra deep hole drilling in a single pass, reducing chip buildup and improving hole quality in long through-holes or blind holes.
• Premium HSS-E material (cobalt-enriched) optimized for longevity across common machining families—steel, stainless steel, and aluminum—so you get longer tool life in mixed-material jobs.
• Extra long length series with a straight shank for broad reach and enhanced accessibility in recessed cavities, deep pockets, or containers where standard-length drills struggle to reach.
• DIN 1869/1 compatibility ensures reliable interchangeability with other DIN-standard tools and consistent performance across tooling setups.

The A976 drill is purpose-built for workshops where depth and precision matter. Its straight shank complements a wide range of chucks and collets, making it a dependable choice for fabricators, automotive shops, machining centers, and hobbyist setups that tackle long, demanding bores without swapping tools.

Who benefits most

• Machinists and shop technicians performing deep-hole work in steel, stainless steel, or aluminum components.
• Engineers developing prototypes or production parts that require long, accurate bores with minimal tool changes.
• Fabricators working in limited-access areas where tool reach is critical and hole depth is a constraint.

Practical usage tips

• Pair with appropriate cutting speeds and feeds for the material—slower speeds for harder steels, moderate speeds for aluminum to minimize built-up edge.
• Use flood/coolant to improve chip evacuation and extend tool life, especially on deep-hole operations.
• Allow for steady, uninterrupted drilling to maximize the parabolic flute’s deep-hole performance; avoid abrupt starts that can deflect the point.
• Inspect the flute condition regularly; a well-maintained edge translates to tighter hole tolerances and longer tool life in sustained drilling tasks.
