Value Collection 01243153 Jobber Drill Bit 3.15 Mm Hss

Product Description

The VALUE COLLECTION 01243153 is a high speed steel (HSS) jobber-length drill bit designed for general-purpose drilling in metal and ferrous materials. With a 3.15 mm diameter and a standard 118-degree split point, it produces clean entry holes in steel and cast iron without requiring a center punch on most prepared surfaces. The oxide coating provides a light layer of surface protection and helps reduce heat buildup during drilling. A web-thinned, tapered web construction reduces cutting resistance at the tip. This bit is sold individually and intended for use in hand drills, drill presses, and CNC equipment by machinists, maintenance technicians, and fabricators.

This jobber drill bit is suited for light to medium material removal in steel and cast iron workpieces. The straight cylindrical shank and standard 3.15 mm diameter make it compatible with most keyed and keyless chucks used in benchtop and floor-standing drill presses, portable electric drills, and machining centers. It is a general-purpose bit appropriate for production and maintenance environments where metric sizing is required.

Key Features

• 3.15 mm diameter with matching straight cylindrical shank for a secure chuck hold
• 118-degree standard point angle for general-purpose drilling in steel and cast iron
• High speed steel (HSS) construction handles moderate heat and maintains edge life
• Oxide surface coating reduces friction and provides basic corrosion resistance
• Web-thinned tapered web lowers thrust requirements and improves chip evacuation
• Two-flute regular spiral design clears chips efficiently in through-hole drilling

Compatibility

Designed as a general-purpose metric jobber drill bit for use in steel and cast iron. Fits standard drill press, hand drill, and machining center chucks sized to accept a 3.15 mm straight shank.

Installation Notes

Install the shank fully and evenly into the chuck before tightening to avoid runout. Ensure the workpiece is securely clamped before drilling. Use appropriate cutting fluid when drilling steel to extend bit life and reduce heat. Inspect the cutting edges before each use and replace the bit if chipping or excessive wear is present.
