Precision Twist Drill 5998868 Screw Machine Drill Bit

Product Description

The PRECISION TWIST DRILL 5998868 is a screw machine length drill bit designed for high-performance drilling in tight-clearance applications. Manufactured from high speed steel with a bright, uncoated finish, this bit features a 118-degree standard point angle and a right-hand spiral flute for efficient chip evacuation. The straight-cylindrical shank seats securely in standard drill chucks. At 0.116 inches in diameter, it matches wire gauge size 32 and is built to ANSI standards for dimensional consistency. The web-thinned, tapered web design reduces thrust and improves hole entry, making this bit a dependable choice for production drilling work.

This bit is sized for screw machine length applications where a shorter overall length provides rigidity and reduced runout. With an overall length of 1-7/8 inches and a flute length of 7/8 inch, it fits compact drilling setups in drill presses, CNC machines, and handheld tools used in light manufacturing and fabrication environments. The primary rated workpiece material is titanium, though the general purpose grade also suits a broad range of ferrous and non-ferrous metals. Machinists, tool and die workers, and industrial maintenance technicians are the typical end users.

Key Features

• 0.116 inch diameter, wire gauge size 32, built to ANSI specification
• High speed steel construction for durability across general-purpose metal drilling
• 118-degree standard point angle with web-thinned, tapered web for reduced entry thrust
• Right-hand cut with regular spiral flute for consistent chip removal
• Screw machine length profile provides added rigidity over jobber-length equivalents
• Bright, uncoated finish — Series R41, high performance grade

Compatibility

Designed as a screw machine length replacement or production drill bit for applications requiring a wire gauge 32 diameter hole in titanium and similar metals; fits any standard straight-shank drill chuck accepting a 0.116 inch shank.

Installation Notes

Install and remove drill bits only with the machine powered down and the spindle fully stopped. Seat the straight-cylindrical shank fully into the chuck and tighten securely before operation to prevent slippage and runout. Use appropriate cutting fluid or coolant for the workpiece material to extend tool life, particularly when drilling titanium or hard alloys. Inspect the cutting edges for wear before each use and replace bits that show chipping or dulling to maintain hole quality and prevent workpiece damage.
