M.a. Ford. 20015400 Solid Carbide Die Drill Bit 0.154 in

Product Description

The M.A. FORD. 20015400 is a solid carbide, straight-flute die drill bit designed for precision holemaking in demanding materials. It carries a 0.1540-inch diameter, a 135-degree split point for self-centering entry, and a web-thinned geometry that reduces thrust and improves chip evacuation. The uncoated carbide construction provides rigidity and edge retention in applications where high-speed steel would deflect or wear prematurely. At 2 inches overall length with a 0.625-inch flute and a 1.375-inch shank, this is a compact, stiff tool built for tight-tolerance die and mold work. Right-hand cutting direction. Diameter tolerance is held to +0.0000 to -0.0005 inches. Machinists, toolmakers, and die makers working in production and tool-room environments are the primary users.

This drill bit is suited for holemaking in cast iron, steel, alloy steel, stainless steel, austenitic stainless steel, titanium, high temperature alloys, non-ferrous metals, hardened materials, ceramics, and glass. The straight-flute design is preferred in brittle or difficult-to-chip materials where a standard spiral flute would induce chatter or material pullout. Die drill bits of this type are commonly used in CNC machining centers, drill presses, and manual knee mills where repeatable, precise hole placement in tool steels and exotic alloys is required. Series 200 designation follows DIN standards.

Key Features

• Solid carbide construction for rigidity and edge retention in hardened and abrasive materials
• 135-degree split point reduces walking and lowers thrust force at entry
• Straight-flute geometry suited for brittle materials including cast iron, ceramics, and glass
• Web-thinned design improves chip clearance and reduces cutting resistance
• Diameter tolerance of +0.0000 to -0.0005 inches supports tight-tolerance hole requirements
• Uncoated finish allows easy inspection for wear and regrinding

Compatibility

Designed for use with standard straight-shank drill chucks and collet systems accepting a 0.1540-inch shank diameter. Rated for primary workpiece materials including cast iron, non-ferrous metals, stainless steel, and steel, with secondary suitability in alloy steel, austenitic stainless steel, ceramics, glass, hardened materials, high temperature alloys, titanium, and other difficult-to-machine materials per Series 200 DIN-standard specifications.

Installation Notes

This tool is installed and operated by machinists and toolmakers on CNC machining centers, drill presses, or manual mills. Secure the shank fully in a collet or drill chuck rated for the 0.1540-inch diameter before operation. Verify spindle runout is within acceptable limits before drilling, as carbide is brittle and sensitive to side-loading. Do not use in hand-held portable drills; this tool requires a rigid, controlled spindle environment.
