M.a. Ford HPDSS2500A Solid Carbide Jobber Drill Bit 1/4 in

Product Description

The M.A. FORD HPDSS2500A is a solid carbide jobber length drill bit engineered for high-performance drilling in demanding trade and industrial applications. Measuring 1/4 inch (0.2500 inch) in diameter with a 140-degree drill point angle, this bit is designed for fast, accurate hole entry with minimal walking. The ALtima coating improves wear resistance and extends tool life in abrasive materials. With an overall length of 79 mm and a flute length of 34 mm, it fits standard drill chucks and CNC setups. Machinists, maintenance technicians, and fabricators working in metals and composite materials are the primary users of this series.

The HPDSS2500A is suited for production and maintenance drilling in ferrous metals, stainless steel, cast iron, and similar hard materials where a high-performance carbide tool is required over standard HSS bits. The 3xD flute-to-diameter ratio supports efficient chip evacuation in short to medium depth holes. Its straight-cylindrical shank with an 8 mm shank diameter seats securely in collet chucks, keyless chucks, and drill press spindles. Right-hand cutting direction is standard for conventional clockwise spindle rotation on mills, lathes, and drill presses.

Key Features

• Solid carbide construction for rigidity and extended tool life in hard materials
• ALtima coating reduces friction and improves wear resistance
• 140-degree drill point angle for aggressive, self-centering entry
• 2 helical flutes promote efficient chip clearance
• Straight-cylindrical shank (8 mm) fits standard collet and keyless chuck systems
• 3xD flute-to-diameter ratio suited for short to medium depth drilling

Compatibility

Designed as an OEM-style replacement and standard tooling option within the M.A. FORD HPDSS series, compatible with any drill press, CNC machining center, or handheld drill accepting a straight-cylindrical shank in the 0.2500 to 0.3000 inch diameter range.

Installation Notes

Installation is performed by machinists or maintenance technicians familiar with rotating cutting tool safety. Ensure the machine spindle is fully stopped and locked out before inserting or removing the bit. Seat the shank fully into the chuck or collet and verify runout before beginning a cut. Coolant-through is not supported on this bit; apply external cutting fluid or coolant at the cutting zone as required by the material being drilled.
