M.a. Ford 20018900 Die Drill Bit 0.1890 Inches Carbide

Product Description

The M.A. FORD 20018900 is a solid carbide, straight-flute die drill bit engineered for precision holemaking in demanding machining applications. It carries a 0.1890-inch diameter (Wire Size 12, 4.80 mm) with a 135-degree split point that reduces walking and lowers thrust force at entry. The uncoated carbide construction delivers consistent edge integrity across high-hardness workpiece materials. Overall length is 2 inches with a 0.625-inch flute length and a 1.375-inch shank. Diameter tolerance is held to +0.0000 to -0.0005 inches, making this bit suitable for close-tolerance die and mold work. Two right-hand cutting flutes handle chip evacuation in the short-flute geometry typical of die drilling operations.

This bit is suited for production and toolroom environments where repeatable, tight-tolerance holes are required in cast iron, steel, alloy steel, stainless steel, austenitic stainless steel, non-ferrous metals, titanium, high-temperature alloys, hardened materials, ceramics, and glass. The Series 200 designation and DIN standard compliance make it a recognized choice for die makers, mold makers, and machinist technicians working on CNC machining centers and manual drill presses requiring short, rigid tooling setups.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• 135-degree split point reduces thrust and self-centers on entry without a pilot hole
• Straight-flute geometry provides added stability in short-chipping materials such as cast iron and hardened steel
• Web-thinned design lowers cutting forces and improves chip clearance
• Tight diameter tolerance of +0.0000 to -0.0005 inches supports close-fit hole requirements
• DIN-standard Series 200 geometry for consistent interchangeability in production tooling programs

Compatibility

Designed as a straight-flute die drill bit per DIN standards, compatible with workpiece materials including cast iron, steel, alloy steel, stainless steel, austenitic stainless steel, non-ferrous metals, titanium, high-temperature alloys, hardened materials, ceramics, and glass.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or toolroom technicians familiar with carbide tooling. Secure the shank fully in a collet or drill chuck rated for the spindle speed required by the workpiece material and bit diameter before beginning any operation. Carbide tooling is brittle — avoid side loading, interrupted cuts without appropriate feed rate reduction, or re-chucking with worn or damaged holders that can induce runout. Inspect the cutting edges before each use; chipped carbide should not be run.
