Value Collection 01358159 Screw Machine Drill Bit Size 15

Product Description

The VALUE COLLECTION 01358159 is a screw machine length drill bit designed for general-purpose drilling in metal, plastic, and similar materials. Built from high-speed steel (HSS) with an oxide coating for added surface hardness and lubricity, this bit cuts a 0.1800-inch diameter hole and features a standard 118-degree point angle for reliable starting on flat and curved surfaces. The shorter-than-jobber overall length of 2-3/16 inches provides increased rigidity and reduced deflection, making it well suited for drill press work and CNC machine operations where stub-length tooling is preferred.

This bit is used in machine shop environments, production drilling applications, and general metalworking setups. The screw machine length format is common in turret lathes, CNC lathes, and machining centers where clearance is limited and rigidity is critical. Licensed machinists, tool-and-die technicians, and production shop operators typically select this format when drilling through ferrous and non-ferrous stock, sheet metal, and structural components requiring consistent hole tolerances in the wire gauge size range.

Key Features

• Wire size 15 corresponds to a 0.1800-inch cutting diameter
• High-speed steel construction handles a wide range of workpiece materials
• Oxide coating improves surface lubricity and reduces heat buildup during cutting
• 118-degree standard point angle with web-thinned tip reduces entry force and walking
• Parallel web configuration and regular spiral flute support consistent chip evacuation
• Straight cylindrical shank fits standard drill chucks and collet holders without adapters

Compatibility

Designed as a general-purpose screw machine length drill bit suitable for use in drill presses, CNC lathes, turret lathes, and machining centers accepting straight-shank tooling in the 0.1500 to 0.2000-inch drill bit size range.

Installation Notes

Installation and use should be performed by qualified machinists or tooling technicians familiar with rotating cutting tools. Secure the shank fully in a properly sized chuck or collet before operation, and verify that the spindle speed is appropriate for the workpiece material and bit diameter. Always power down and lock out the machine before changing tooling. Do not exceed the designed cutting parameters for HSS tooling in hardened materials.
