M.a. Ford. Hpdss 0400A Carbide Jobber Drill Bit 4 Mm

Product Description

The M.A. FORD. HPDSS 0400A is a solid carbide jobber-length drill bit engineered for high-performance drilling in demanding shop and field applications. It measures 4 mm in diameter (0.1575 inches decimal equivalent) with a 66 mm (2.6 inches) overall length and a 24 mm flute length. The 140-degree split-point geometry reduces walking and enables fast penetration without a center punch. The ALtima coating provides thermal and wear resistance, extending tool life in ferrous and non-ferrous materials. This bit is suited for machinists, toolmakers, and precision fabricators working on CNC equipment or manual drill presses.

The HPDSS 0400A is designed for jobber-length drilling tasks in production and maintenance machining environments. The 3xD flute-to-diameter ratio makes it well suited for moderate-depth holes in materials such as steel, cast iron, aluminum, and similar workpiece materials. The straight-cylindrical shank seats securely in standard drill chucks and collets without requiring a morse taper adapter. It is appropriate for both CNC machining centers and bench-mounted drill presses in industrial and trade shop settings.

Key Features

• Solid carbide construction delivers rigidity and heat resistance beyond high-speed steel alternatives
• ALtima coating reduces friction and extends cutting edge life in high-cycle applications
• 140-degree point angle minimizes drill walk and improves hole entry accuracy
• Right-hand helical flute design promotes efficient chip evacuation
• Straight-cylindrical shank fits standard drill chucks and ER collet systems
• 3xD flute-to-diameter ratio balances chip clearance with core strength

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide jobber drill bit for standard 4 mm diameter drilling applications across compatible CNC machining centers and manual drill press setups.

Installation Notes

Installation and tool changes should be performed with the machine powered down and the spindle fully stopped. Secure the straight-cylindrical shank in a properly sized drill chuck or collet to the manufacturer-recommended clamping depth before operation. Solid carbide tooling is brittle compared to high-speed steel and should not be used in setups with excessive runout or lateral loading. Verify spindle speed and feed rate against the recommended parameters for the workpiece material before engaging the cut.
