Precision Twist Drill 5998793 Screw Machine Drill Bit

Product Description

The PRECISION TWIST DRILL 5998793 is a screw machine length drill bit engineered for high-performance drilling in demanding trade and industrial applications. Measuring 0.182 inches (Wire Size 14) in diameter with an overall length of 2-3/16 inches and a flute length of 1-1/8 inches, this bit is built from high speed steel with a bright, uncoated finish. It features a 118-degree standard point angle, a right-hand spiral flute, and a straight-cylindrical shank. The shortened screw machine length body improves rigidity and reduces deflection in drill press and turret lathe operations.

This drill bit is suited for use in machine shops, maintenance facilities, and production environments where shorter-body bits are required for drilling in tight clearances or on automated equipment. The Series R41 designation identifies it as a web-thinned, tapered-web design with a 2.5xD flute-to-diameter ratio, making it appropriate for cutting through tough workpiece materials including titanium. It meets ANSI standards and carries a general purpose grade classification, making it a reliable choice for a wide range of material removal tasks.

Key Features

• 0.182 inch diameter (Wire Size 14) for precise hole sizing
• High speed steel construction for durability in production drilling
• 118-degree standard point angle for accurate starting and reduced walking
• Web-thinned, tapered-web design reduces cutting force and heat buildup
• Screw machine length body increases rigidity and minimizes deflection
• Bright/uncoated finish; right-hand cut with spiral flute geometry

Compatibility

Designed for use in screw machines, drill presses, and turret lathes requiring straight-cylindrical shank bits in the 0.1500 to 0.2000 inch diameter range. Listed primary workpiece material is titanium, though the general purpose grade is suitable for a variety of metals and alloys within that diameter class.

Installation Notes

Installation is performed by machinists or maintenance technicians familiar with drill press, lathe, or CNC equipment. Secure the straight-cylindrical shank firmly in a collet or chuck before use, and verify chuck runout is within acceptable tolerance to protect bit geometry. Always wear appropriate eye protection and ensure the workpiece is properly fixtured. Operate at speeds and feeds appropriate for the workpiece material and bit diameter per standard machining practice.
