Precision Twist Drill 5998574 7/32 in Screw Machine Drill Bit

Product Description

The PRECISION TWIST DRILL 5998574 is a screw machine length drill bit designed for high-performance drilling in a wide range of materials, with a primary rating for titanium and other demanding workpiece materials. It measures 7/32 inch (0.2188 inches) in diameter with an overall length of 2-3/8 inches and a flute length of 1-1/4 inches. The bit is manufactured from high speed steel with a bright, uncoated finish and features a 118-degree standard point angle with web thinning for improved penetration and reduced thrust. It is part of the Series R40 line and conforms to ANSI standards. Machinists, toolroom technicians, and maintenance professionals install this bit in standard drill chucks and CNC turret setups.

This bit is built for screw machine length applications where a shorter, stiffer body reduces deflection in close-tolerance boring and production drilling. The straight-cylindrical shank fits standard drill chucks without adapters. A 2.5xD flute-to-diameter ratio and tapered web configuration support chip evacuation in interrupted cuts and through-hole operations. It is suited for use in manual drill presses, turret lathes, and CNC machining centers. The bright finish makes it appropriate for a broad range of ferrous and non-ferrous materials where coating compatibility is a consideration. Each package contains one drill bit, sold in multiples of 12.

Key Features

• 7/32 inch (0.2188 inches) diameter with a compact screw machine length body of 2-3/8 inches overall
• High speed steel construction rated for general purpose and high-performance drilling including titanium
• 118-degree standard point angle with web thinning for lower thrust and cleaner entry
• Tapered web configuration with spiral flutes for consistent chip evacuation
• Straight-cylindrical shank for direct chuck mounting without adapters
• Bright, uncoated finish compatible with a wide range of workpiece materials

Compatibility

Designed as an OEM-style replacement and general-use screw machine drill bit conforming to ANSI standards, Series R40, suitable for use in standard drill chucks accepting a straight-cylindrical shank in the 0.2000 to 0.2500 inch diameter range.

Installation Notes

This bit is installed by machinists and toolroom technicians in drill presses, turret lathes, and CNC machining centers. Before bit changes, power down the machine and confirm the spindle has fully stopped. Secure the straight-cylindrical shank firmly in the chuck to the full depth of the jaws to minimize runout and deflection. Follow the machine manufacturer and applicable workplace safety guidelines for speeds, feeds, and coolant use when drilling titanium or other high-resistance materials.
