M.a. Ford. 20606700 Solid Carbide Screw Machine Drill Bit

Product Description

The M.A. FORD. 20606700 is a solid carbide screw machine length drill bit with a 0.067 inch (wire size 51) diameter and a 118-degree faceted point angle. Designed for high-precision drilling in demanding trade and industrial environments, this bit delivers consistent performance in applications where standard high-speed steel tooling falls short. The bright/uncoated finish suits a wide range of cutting fluids and dry-cutting scenarios. With a short overall length of 1.5 inches and a parallel web configuration with web thinning, the geometry supports accurate entry and reduced thrust when drilling into tough materials.

This drill bit is suited for machining operations involving cast iron, non-ferrous metals, stainless steel, and steel. Its screw machine length profile makes it a practical choice for CNC drilling, manual drill press work, and precision hand-tool applications where stub-length rigidity reduces deflection. The straight cylindrical shank allows direct chuck mounting without adapters. It is commonly used by machinists, tool-and-die technicians, and precision fabricators working in production or maintenance environments.

Key Features

• Solid carbide construction for extended tool life in hard and abrasive workpiece materials
• 118-degree faceted drill point with web thinning for accurate entry and reduced thrust force
• Screw machine (short) length at 1.5 inches overall for maximum rigidity and minimal deflection
• Right-hand cut with regular spiral flute geometry, 2 flutes, 3xD flute-to-diameter ratio
• Straight cylindrical shank at 0.067 inches diameter for standard chuck compatibility
• Diameter tolerance held to +0.0000 to -0.0005 inches for repeatable, precision-fit holes
• Compatible with cast iron, non-ferrous metals, stainless steel, and carbon steel workpieces

Compatibility

Designed for use with cast iron, non-ferrous metal, stainless steel, and steel workpieces as specified by the manufacturer. Fits standard drill chucks accepting a 0.067 inch straight cylindrical shank. Part of M.A. FORD. Series 206 screw machine length solid carbide drill bits covering the 0.0000 to 0.1000 inch diameter range.

Installation Notes

Installation and use should be performed by qualified machinists or tooling technicians familiar with carbide cutting tool handling. Secure the shank fully in a properly sized collet or drill chuck before operation, and verify runout is within acceptable limits to prevent premature tool breakage. Solid carbide tooling is brittle and should never be used in setups with excessive vibration or unsupported workpieces. Always power down and lock out the machine before changing or inspecting the bit.
