Meet the Dormer Pramet A976 1.50 mm HSS-E High Performance Multi-Application Straight Shank Extra Long Series drill (DIN 1869 / 1). This compact, precision-focused drill is built for operators who demand accurate starts, deep reach, and reliable performance across a range of materials.

Why this drill stands out

• 130-degree point for self-centering begins every hole with minimal guidance and lowers the push force required, helping you maintain control and reduce chatter at the start of drilling.
• Bright finish minimizes friction aid and prevents workpiece material from sticking to the cutting edge, producing cleaner holes and easier chip evacuation.
• Parabolic flute design engineered to pull chips efficiently and sustain cutting efficiency when drilling very deep holes in a single pass.
• Premium HSS-E material combines high-speed steel with cobalt-enhanced toughness, enabling dependable drilling through a variety of metals including steel, aluminum, and stainless steel.
• Extra long length designed for deep-hole work and applications where extended reach is essential—perfect when standard drills can’t access recessed areas or long through-holes.
• DIN 1869 / 1 compatibility ensures consistent fit with standard drill bushings, chucks, and holders found in industrial setups.

Ideal use cases

This drill excels in situations where depth matters: drilling long blind holes in engine components, transmission housings, die casts, mold bases, or anywhere you need a precise hole that reaches deep into the workpiece without multiple passes. The 1.50 mm diameter makes it a precise choice for fine-feature drilling, micro-machining tasks, and detailed fabrication work where control and longevity matter.

How it helps your workflow

• Reduces start-up force and improves hole start accuracy, saving time on setup and increasing first-pass success rates.
• Delivers cleaner holes with less material buildup, which reduces post-drilling deburring and part finishing work.
• Maintains cutting efficiency through deeper reach thanks to the parabolic flute geometry, minimizing interruptions and tool changes.
• Versatile enough to handle multiple materials—steel, stainless steel, and aluminum—without swapping tools for each job.
• Extends your capabilities in tall assemblies, fixtures, and assemblies with restricted clearance where standard-length drills fall short.

Practical tips for best results

• Use steady, axial feed to keep the cutting edge engaged and preserve the 130° point geometry.
• Apply appropriate lubrication or cutting fluid based on material to reduce heat and wear, especially on stainless steel.
• For deep holes, leverage the parabolic flute to evacuate chips efficiently; pause to clear chips if you encounter resistance.
• Inspect the drill tip and flute after every few holes; replace if you notice chips, gouges, or loss of geometry to avoid poor hole quality.

With the Dormer Pramet A976 1.50 mm HSS-E High Performance Multi-Application Straight Shank Extra Long Series drill, you’re equipping your shop with a tool designed to tackle the most demanding deep-hole tasks with precision and reliability. It’s the choice for professional machinists who demand consistent results and fewer tool changes in high-precision environments.
