Precision Twist Drill 5999414 Screw Machine Drill Bit

Product Description

The PRECISION TWIST DRILL 5999414 is a screw machine length drill bit designed for precision drilling in tight-clearance and high-cycle applications. Built from high speed steel with a bright, uncoated finish, this bit features a 118-degree standard point angle and a web-thinned, tapered web configuration that reduces thrust and improves centering on entry. The straight-cylindrical shank seats securely in standard drill chucks and quick-change holders. At 0.096 inches in diameter with an overall length of 1-13/16 inches, this bit fits where standard jobber-length drills cannot. It is rated for high performance use and conforms to ANSI standards.

This drill bit is suited for production and maintenance drilling environments where short, rigid cutting tools are required. The screw machine length format reduces deflection and improves hole accuracy in CNC machining centers, drill presses, and hand-held power tools. The Series R41 designation places this bit in a general purpose grade intended for a wide range of metalworking tasks. The primary workpiece material listed is titanium, though the high speed steel construction and general purpose grade make it applicable across a broad range of metals encountered in trade and shop settings. The right-hand spiral flute design evacuates chips efficiently during drilling.

Key Features

• 0.096 inch diameter wire size corresponds to Wire Gauge 41
• High speed steel construction for durability in metalworking applications
• Web-thinned tapered web reduces entry thrust and improves point centering
• 118-degree standard point angle for general purpose drilling
• Screw machine length at 1-13/16 inches overall for rigid, low-deflection performance
• Conforms to ANSI standards for consistent dimensional accuracy

Compatibility

Designed as an OEM-style replacement or standard production drill bit for use in screw machine, CNC, and general metalworking drilling applications requiring a straight-cylindrical shank bit in the Wire Gauge 41 size range.

Installation Notes

Installation and use should be performed by a qualified machinist or trained trade professional familiar with metal drilling operations. Secure the straight-cylindrical shank fully in the chuck before operation and verify runout is within acceptable tolerance. Power down or de-energize all equipment before changing or inspecting bits. Follow shop safety protocols and applicable ANSI machining standards when operating drilling equipment.
