Dormer Pramet A510 3.80 mm HSS TiN ADX STRAIGHT SHANK JOBBER DRILL DIN 338

The Dormer Pramet A510 3.80 mm HSS TiN ADX Straight Shank Jobber Drill (DIN 338) is a precision twist drill designed for reliable hole making in a variety of materials. With a straight shank and DIN 338 sizing, it fits standard chucks and tooling setups, making it a practical choice for both shop floors and workstation projects. The 3.80 mm diameter keeps holes tight and accurate for applications ranging from metal fabrication to cabinetry and hobbyist projects.

Key features work together to deliver consistent results: a 130° thinned point helps with self-centering and reduces the push force required to start a hole, easing operation and improving first-pass accuracy; a Titanium Nitride coating extends tool life and enhances performance when drilling harder materials; convex cutting edges promote efficient chip breakage for easier removal, enabling higher cutting speeds and feeds.

• 130° Thinned Point: Promotes self-centering and lowers starting resistance, delivering cleaner holes with less effort and greater first-pass accuracy.
• TiN Coating for Longer Life: Hard-wearing surface reduces wear at high speeds, preserving edge sharpness and enabling more holes per edge when drilling steels, aluminum, and stainless steels.
• Convex Cutting Edges: Aids in breaking chips for smoother evacuation, supporting higher feeds and speeds while maintaining hole quality and reducing downtime.

Designed for real-world use, this drill delivers dependable performance across common metals and alloys, helping you achieve high-quality, accurately sized holes (H9 tolerance) quickly and consistently. The combination of a premium HSS core, TiN coating, and chip-friendly geometry makes it a trustworthy addition to any toolbox, reducing setup time and improving workflow on busy days.
