M.a. Ford. 20003300 Die Drill Bit 0.0330 in Carbide

Product Description

The M.A. FORD. 20003300 is a solid carbide, straight-flute die drill bit designed for precision holemaking in demanding materials. It features a 0.0330 inch diameter, a 135-degree split point for accurate self-centering and reduced thrust, and a web-thinned geometry that improves chip evacuation. The two-flute, right-hand cutting design provides clean entry in tight tolerances. With an overall length of 1.5 inches and a flute length of 0.2188 inches, this bit is built for controlled drilling in tool and die work, mold making, and precision machining operations. It is sized to wire gauge number 66. Machinists and tool and die makers are the primary installers and operators of this bit.

This drill bit is suited for holemaking in cast iron, non-ferrous metals, stainless steel, alloy steel, austenitic stainless steel, hardened materials, high-temperature alloys, titanium, ceramic, and glass. Its solid carbide construction and uncoated finish make it appropriate for applications requiring close dimensional control and sharp cutting edges. The split point and web-thinned design reduce walking and heat buildup at entry, making it a reliable choice for small-diameter work on CNC machining centers, drill presses, and manual jig boring operations where precision is critical.

Key Features

• 0.0330 inch diameter with diameter tolerance of +0.0000 to -0.0005 inches for tight fitment requirements
• 135-degree split point reduces thrust and improves self-centering on entry
• Web-thinned geometry promotes efficient chip evacuation in deep holes
• Solid carbide construction provides rigidity and wear resistance in hard and abrasive materials
• Straight-flute, two-flute design optimized for small-diameter die and mold work
• Conforms to DIN standards for dimensional consistency

Compatibility

Designed as an OEM-style precision drill bit for use in tool and die, mold making, and general precision holemaking applications across compatible CNC and manual drilling equipment.

Installation Notes

This drill bit is installed and operated by machinists and tool and die professionals using appropriate collets or chucks rated for small-diameter tooling. Ensure the spindle and workholding are clean and concentric before seating the bit to avoid runout that can fracture carbide at this diameter. Always verify spindle speed and feed rate against the workpiece material before operation. Carbide tooling is brittle and must not be used in setups with excessive vibration or backlash.
