M.a. Ford 30612600 Circuit Board Drill Bit 3.2mm

Product Description

The M.A. FORD 30612600 is a solid carbide fast spiral drill bit engineered for precision circuit board drilling. It features a 165-degree drill point angle optimized for clean entry and exit in thin, layered materials. The fast spiral geometry with a 35-degree helix angle promotes efficient chip evacuation and reduces heat buildup during high-speed drilling operations. With a 3.2mm cutting diameter and a 1/8-inch (3.18mm) shank diameter, this bit fits standard circuit board drilling chucks and spindles. The tapered web configuration adds rigidity and helps maintain accuracy in demanding production or repair environments. Licensed HVAC and electronics technicians, PCB fabricators, and precision machinists are the typical users.

This drill bit is suited for circuit board drilling applications across a wide range of workpiece materials including alloy steel, carbon steel, cast iron, stainless steel, high-temperature alloys, and titanium. It performs in both production environments and field repair scenarios where precise small-diameter holes are required. The 12.2mm flute length accommodates standard PCB stack thicknesses, and the 38mm overall length is compatible with common drill press and CNC spindle setups. Right-hand cutting direction is standard for conventional drill press and CNC routing equipment.

Key Features

• Solid carbide construction for wear resistance and rigidity in hard and abrasive materials
• 165-degree drill point angle designed for clean penetration in circuit board and thin-material applications
• Fast spiral with 35-degree helix angle for efficient chip evacuation and reduced heat
• Tapered web configuration adds strength and helps maintain drill accuracy
• 3.2mm cutting diameter with a 1/8-inch shank for compatibility with standard toolholders
• Right-hand cutting direction suits conventional and CNC drilling equipment

Compatibility

Designed as an OEM-style replacement or production drill bit for use in standard circuit board drilling applications; fits toolholders and spindles accepting a 1/8-inch (3.18mm) round shank.

Installation Notes

Installation and use of this bit should be performed by qualified machinists or electronics fabrication technicians familiar with CNC or manual drill press operation. Ensure the machine spindle is fully stopped and powered down before changing tooling. Secure the shank firmly in the collet or chuck to the equipment manufacturer's specified clamping method to prevent runout. Inspect the bit for chipping or wear before each use, as solid carbide bits can fracture if used in damaged condition or at incorrect speeds and feeds.
