Value Collection 01188317 No 31 Hss Jobber Drill Bit

Product Description

The VALUE COLLECTION 01188317 is a No. 31 wire-size jobber-length drill bit designed for general-purpose drilling in steel, cast iron, and similar ferrous materials. Built from high speed steel (HSS) with an oxide coating, it provides adequate wear resistance and heat dissipation for everyday shop and field drilling tasks. The 118-degree standard point angle is the conventional geometry for drilling into metals, offering a balance of cutting aggressiveness and point stability. With a 0.120-inch diameter and an overall length of 2.75 inches, this bit fits standard three-jaw drill chucks and is sized for typical pilot holes, clearance holes, and through-hole applications encountered by machinists, plumbers, electricians, and HVAC technicians.

This jobber drill bit suits residential and light commercial trade work where a No. 31 wire gauge hole is required. Common applications include drilling pilot holes for self-tapping screws, clearance holes for No. 8 fasteners, and general metalwork in steel and cast iron stock. The straight cylindrical shank accepts any standard drill chuck. It is sold individually but requires a minimum order of 12 units, making it appropriate for shop restocking or tool crib replenishment.

Key Features

• No. 31 wire size, 0.120-inch diameter for precise hole sizing in metal stock
• 118-degree standard point angle suits general-purpose drilling in steel and cast iron
• High speed steel construction withstands the heat and friction of metal drilling
• Oxide coating reduces friction and provides basic corrosion resistance
• Web-thinned tapered web improves penetration and reduces thrust requirements
• Right-hand cutting, regular spiral flute with straight cylindrical shank for universal chuck compatibility

Compatibility

Designed as a general-purpose jobber drill bit compatible with any standard drill chuck accepting a 0.120-inch straight cylindrical shank. Rated for drilling into steel and cast iron workpieces.

Installation Notes

Installation is performed by machinists, maintenance technicians, and trade professionals using a handheld drill, drill press, or similar rotary tool. Secure the workpiece before drilling and use appropriate cutting fluid or lubricant when drilling ferrous metals to extend bit life. Always wear appropriate eye protection. Follow applicable shop safety and OSHA guidelines when operating rotary cutting tools.
