M.a. Ford. 30008070 Circuit Board Drill Bit 2.05 Mm Carbide

Product Description

The M.A. FORD. 30008070 is a solid carbide circuit board drill bit engineered for high-precision drilling in printed circuit board fabrication and related electronic assembly applications. Sized at 2.05 mm in diameter, this two-flute bit features a 118-degree point angle and a fast spiral with a 35-degree helix angle, designed to evacuate chips quickly while maintaining hole accuracy. The bright, uncoated solid carbide construction delivers rigidity and wear resistance without a coating layer that could alter the cutting edge geometry at tight tolerances. Machinists and PCB fabrication technicians are the primary installers of this bit.

This drill bit is suited for precision drilling in cast iron, non-ferrous metals, and steel workpieces. The fast spiral geometry makes it particularly effective in high-speed CNC drilling operations common in circuit board and light metalwork environments. With a 2.05 mm diameter and 16.00 mm flute length, it is built for controlled, repeatable hole placement in thin or layered materials. It fits machines and toolholders accepting a straight shank of 2.05 mm diameter.

Key Features

• Solid carbide construction for rigidity and long tool life in precision drilling applications
• 2.05 mm cutting diameter with a matching 2.05 mm straight shank for direct toolholder fitment
• 118-degree point angle for consistent entry geometry in cast iron, non-ferrous metal, and steel
• Fast spiral with 35-degree helix angle for efficient chip evacuation
• Bright, uncoated finish maintains precise edge geometry at tight diameter tolerances (-0.013 to 0.000 mm)
• Right-hand cut, two-flute design compatible with standard CNC and high-speed drilling spindles

Compatibility

Designed for use with cast iron, non-ferrous metal, and steel workpieces. Fits standard toolholders and collets accepting a 2.05 mm straight shank.

Installation Notes

This bit is typically installed by machinists or CNC operators in drill presses, CNC machining centers, or dedicated PCB drilling machines. Ensure the spindle and toolholder are clean and free of debris before seating the shank. Set spindle speed according to the workpiece material and machine manufacturer guidelines for the 2.05 mm diameter range. Inspect the cutting edges before each use and replace the bit if chipping or wear is observed, as carbide bits can fracture if run on a damaged edge.
