M.a. Ford HPDCS1285A Screw Machine Drill Bit Size 30

Product Description

The M.A. FORD HPDCS1285A is a screw machine length drill bit engineered for high-performance drilling in tight-tolerance applications. Built from solid carbide with an ALtima coating, it delivers extended tool life and thermal resistance in demanding production environments. The 140-degree split point promotes self-centering and reduces thrust, minimizing workpiece walking on entry. With a 2-flute spiral design and through-coolant capability, this bit handles high-speed drilling in steel, cast iron, stainless, and non-ferrous materials. It is sized at wire gauge number 30, equivalent to 0.1285 inches in decimal, and runs right-hand cutting with a straight-cylindrical shank measuring 4.00 millimeters in diameter.

This bit belongs to M.A. FORD's HPDCS series, rated as a high-performance grade tool suited for CNC machining centers, drill presses, and screw machine operations. It fits production shops, tool rooms, and precision machining environments where consistent hole quality and repeatability matter. The short screw machine length body improves rigidity and reduces deflection in high-feed drilling cycles, making it appropriate for both through-holes and short blind bores. A 3xD flute-to-diameter ratio supports effective chip evacuation when paired with coolant delivery.

Key Features

• Solid carbide construction for rigidity and wear resistance at elevated cutting speeds
• ALtima coating extends tool life and reduces built-up edge in ferrous and hard materials
• 140-degree drill point angle promotes self-centering and reduces entry thrust
• Through-coolant capability supports high-speed, high-feed drilling cycles
• Screw machine length body improves rigidity and minimizes deflection
• Right-hand, 2-flute spiral design for efficient chip evacuation

Compatibility

Designed for use in CNC machining centers and screw machines requiring a wire gauge number 30 (0.1285 inch) diameter hole with a straight-cylindrical shank fitting a 4.00 millimeter collet or chuck.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and machine power locked out. Ensure the straight-cylindrical shank is seated fully and clamped securely in a compatible collet, chuck, or toolholder before operation. Through-coolant lines should be confirmed clear and at the recommended pressure for the machine before running. Inspect the cutting edges for chips or coating damage before each use and replace if wear is visible.
