Value Collection 01391200 Taper Length Drill Bit Hss

Product Description

The VALUE COLLECTION 01391200 is a taper length twist drill bit designed for general-purpose drilling in metal, wood, and similar materials. It measures 0.1260 inches (3.20 mm) in diameter with a 118-degree standard drill point angle, which is the industry-standard geometry for drilling into most common workpiece materials. The bit is manufactured from high-speed steel (HSS) with a black oxide finish to reduce friction and provide moderate corrosion resistance during use. A web-thinned, tapered web configuration reduces thrust required at the cutting edge, improving chip evacuation and hole entry performance.

This drill bit is suited for trade and production drilling applications where a longer flute length is needed to reach greater depths than a standard jobber-length bit allows. The taper length body gives the drill added rigidity while maintaining reach. With a straight-cylindrical shank, it seats directly into standard 3-jaw drill chucks found on drill presses, hand drills, and milling machine setups. Right-hand spiral flutes clear chips upward and out of the hole during normal clockwise rotation. General-purpose grade makes it appropriate for maintenance, fabrication, and light production work.

Key Features

• 0.1260 inch (3.20 mm) diameter with standard 118-degree point angle for broad material compatibility
• HSS construction handles elevated cutting temperatures better than carbon steel
• Black oxide finish reduces friction and provides light corrosion resistance
• Web-thinned tapered web reduces drilling thrust and improves hole entry
• Taper length flute at 69.00 mm provides extended reach over standard jobber-length bits
• Straight-cylindrical shank fits standard 3-jaw drill chucks without adapters
• Right-hand cut with regular spiral flutes for efficient chip removal

Compatibility

Designed as a general-purpose taper length drill bit compatible with any standard 3-jaw drill chuck that accommodates a straight-cylindrical shank of this diameter.

Installation Notes

This bit is installed and removed by a licensed or qualified machinist, fabricator, or maintenance technician using a standard keyed or keyless drill chuck. Secure the shank fully in the chuck before operation and verify chuck key is removed before starting the spindle. Use appropriate cutting fluid or lubricant when drilling metals to extend bit life and improve surface finish. Inspect the cutting edges for wear or chipping before each use and replace the bit if the point is damaged to avoid workpiece damage or breakage.
