M.a. Ford 30001970 Circuit Board Drill Bit 0.5 Mm Carbide

Product Description

The M.A. FORD 30001970 is a solid carbide circuit board drill bit engineered for precision drilling in printed circuit board (PCB) fabrication and related small-hole applications. Built from uncoated solid carbide, this bit delivers the rigidity and edge retention required when drilling tight-tolerance holes in dense or abrasive materials. It features a 118-degree point angle and a fast spiral design with a 35-degree helix angle, promoting clean chip evacuation and reduced heat buildup during high-speed operation. The 0.5 mm diameter and compact 38 mm overall length make it well suited for CNC drilling machines and precision drill presses used in electronics manufacturing and PCB prototyping.

This drill bit is intended for use in environments where small-diameter, high-precision holes are critical. It is suited for drilling cast iron, non-ferrous metals, and steel, making it applicable beyond PCB work to include fine metalworking and precision machining tasks. The right-hand cutting direction is compatible with standard drill press and CNC spindle setups. Machinists, electronics fabricators, and precision metalworking shops will find this bit appropriate for repetitive small-hole drilling where consistent diameter tolerance is required. The drill bit diameter tolerance is held to -0.013 to 0.000 mm, supporting tight fitment standards.

Key Features

• Solid carbide construction for high rigidity and extended tool life in abrasive materials
• 118-degree point angle for accurate entry and reduced walking on hard surfaces
• Fast spiral with 35-degree helix angle promotes efficient chip evacuation
• Bright uncoated finish suitable for non-ferrous metals, cast iron, and steel
• Right-hand cut compatible with standard CNC and manual drill spindles
• Tight diameter tolerance of -0.013 to 0.000 mm for precision hole sizing

Compatibility

Designed as an OEM-style replacement or direct-use drill bit for CNC PCB drilling machines and precision drill presses that accept 0.5 mm shank tooling in standard collet or chuck systems.

Installation Notes

This drill bit is installed by qualified machinists or electronics fabrication technicians using appropriately sized collets or chucks rated for 0.5 mm shank tooling. Verify spindle speed and feed rate settings are appropriate for the workpiece material before operation, as carbide tooling is brittle and susceptible to fracture from side loading or excessive feed pressure. Always power down and de-energize the machine before changing tooling. Handle carbide drill bits carefully to avoid chipping the cutting edges during storage and setup.
