Value Collection 01358217 Screw Machine Drill Bit Size 21

Product Description

The VALUE COLLECTION 01358217 is a screw machine length drill bit designed for high-speed drilling in metal, wood, and plastic applications. Built from high-speed steel (HSS) with an oxide coating for added lubricity and corrosion resistance, this bit measures 2.125 inches in overall length with a 1.0625-inch flute length. The 118-degree standard point angle provides reliable starting and fast penetration on general-purpose materials. The straight cylindrical shank is compatible with standard drill chucks. This bit is sold individually and is sized at wire gauge No. 21, equivalent to 0.1590 inches in diameter.

This drill bit is suited for screw machine and production drilling applications where a shorter, more rigid bit is required. The reduced overall length compared to jobber-length bits minimizes deflection in tight clearance situations. Machinists, tool and die workers, and general fabrication shops rely on screw machine length bits for repetitive hole-making operations in light to medium stock materials. The 2-flute regular spiral configuration provides efficient chip evacuation during through-hole drilling.

Key Features

• Wire gauge size No. 21 — 0.1590 inch diameter for precise hole sizing
• 118-degree standard point angle for general-purpose drilling
• High-speed steel construction with oxide finish for durability and lubricity
• Screw machine length body reduces deflection in tight-clearance setups
• 2-flute regular spiral design promotes efficient chip removal
• Web-thinned parallel web for reduced thrust and easier starting

Compatibility

Designed as a general-purpose screw machine length drill bit compatible with standard drill chucks and screw machine setups accepting straight-shank bits in the 0.1500 to 0.2000 inch diameter range.

Installation Notes

Installation is performed by machinists or toolroom technicians using standard drill press, CNC, or screw machine equipment. Secure the straight shank firmly in a properly sized chuck before operation. Ensure the workpiece is clamped or fixtured to prevent movement during drilling. Follow applicable shop safety guidelines and wear appropriate eye protection when operating drilling equipment.
