M.a. Ford. 22641340 Solid Carbide Screw Machine Drill Bit

Product Description

The M.A. FORD. 22641340 is a solid carbide screw machine length drill bit designed for high-precision drilling in demanding materials. It measures 0.4134 inches (10.50 mm) in diameter with an overall length of 3.5039 inches (89.00 mm) and a flute length of 1.6929 inches (43.00 mm). The 118-degree faceted point geometry and web-thinned construction reduce entry force and improve chip evacuation. The bright, uncoated finish is standard for solid carbide tooling used across a wide range of ferrous and non-ferrous applications. This bit is installed by machinists, tool and die technicians, and precision fabrication professionals.

The 22641340 is intended for short-length, high-rigidity drilling operations where chatter and deflection must be minimized. Primary workpiece materials include cast iron, non-ferrous metals, stainless steel, and steel. The stub-length body provides extra stiffness compared to jobber-length drills, making it a practical choice for CNC machining centers, drill presses, and manual machine work where hole depth is limited and accuracy is critical. The straight-cylindrical shank seats directly in standard drill chucks or collet holders without modification.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• 118-degree faceted drill point with web thinning for reduced thrust and cleaner entry
• Screw machine (stub) length provides increased stiffness and reduced deflection
• Right-hand spiral flute with regular helix for consistent chip removal
• Straight-cylindrical shank at 0.4134 inches diameter fits standard chucks and collets
• Conforms to DIN 6539 specification for dimensional consistency

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide stub drill for machine tool applications requiring a 0.4134-inch (10.50 mm) diameter bit in the M.A. FORD. Series 226 product line. Compatible with any standard drill chuck or collet system accepting a 0.4134-inch straight-cylindrical shank.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully and evenly in the chuck or collet holder and verify runout before beginning a cut. Solid carbide tooling is brittle — avoid side loading, interrupted cuts without proper feed rate adjustment, and re-chucking a bit that shows visible chipping or cracking.
