Value Collection 01358506 Size 50 Screw Machine Drill Bit Hss

Product Description

The VALUE COLLECTION 01358506 is a screw machine length drill bit designed for close-tolerance drilling in metal, wood, and plastic. Built from high-speed steel (HSS) with an oxide coating, it offers improved wear resistance and reduced friction during drilling operations. The bit measures 0.0700 inches in diameter (wire size 50) with an overall length of 1-11/16 inches and a flute length of 11/16 inches. The short body length of screw machine bits provides added rigidity over jobber-length bits, making this format a preferred choice for machinists and shop technicians working in drill presses, CNC machines, and turret lathes.

This bit is suited for general-purpose drilling in production and maintenance environments where a small-diameter, short-length tool is required. The 118-degree standard point angle is appropriate for a wide range of common workpiece materials. Right-hand cutting direction makes it compatible with standard drill presses and hand drills. Typical applications include tapping pilot holes, fine detail work, and light-duty hole production in metal fabrication, machining shops, and maintenance facilities.

Key Features

• Wire size 50 diameter at 0.0700 inches for precise small-diameter drilling
• HSS construction with oxide coating for improved wear resistance and heat reduction
• 118-degree standard point angle suits general-purpose material entry
• Screw machine length body (1-11/16 inches OAL) provides increased rigidity over jobber-length bits
• Web-thinned tip reduces thrust force and improves chip evacuation
• Straight cylindrical shank fits standard drill chucks without adapters
• Regular spiral flute with 2-flute configuration for consistent chip clearance

Compatibility

Designed as a general-purpose screw machine length drill bit compatible with standard drill chucks accepting straight cylindrical shanks in the 0.0000 to 0.1000 inch decimal inch size range.

Installation Notes

A licensed machinist or qualified technician should secure the shank fully in the drill chuck before operation and verify chuck runout on precision applications. Ensure the workpiece is firmly clamped or fixtured before drilling to prevent walking at small diameters. Apply cutting fluid appropriate for the workpiece material to extend bit life and maintain hole quality. Inspect the cutting edges before each use, as small-diameter HSS bits are susceptible to breakage if deflected or run at incorrect speeds.
