Value Collection 81430100 5/32 in Hss Jobber Drill Bit

Product Description

The VALUE COLLECTION 81430100 is a 5/32 inch (0.1562 inch decimal) high speed steel jobber drill bit designed for general-purpose drilling in metal and ferrous materials. The 135-degree split point geometry reduces walking at drill entry and lowers the thrust force needed to start a hole, making it well suited for production drilling and repetitive hole-making tasks. The parabolic flute profile improves chip evacuation in deeper holes, reducing heat buildup and the need to peck-drill as frequently. At 3.125 inches overall length with a 2 inch flute length, this is a standard jobber-length format appropriate for the majority of benchtop and handheld drilling applications. Installation and setup require no special tooling beyond a standard chuck.

This drill bit is intended for right-hand cutting in steel, cast iron, and similar ferrous workpieces. The bright uncoated finish makes it a cost-effective choice for general shop use where coated tooling is not required. The straight cylindrical shank at 0.1563 inch diameter seats directly in keyed or keyless chucks without an adapter. It is commonly used by machinists, pipefitters, electricians, HVAC technicians, and maintenance tradespeople for drilling pilot holes, clearance holes, and through-holes in sheet metal, structural steel, pipe, and enclosure panels.

Key Features

• 135-degree split point reduces drill walk and lowers entry thrust force
• Parabolic flute geometry accelerates chip removal in deeper cuts
• High speed steel construction handles steel and cast iron workpieces
• Web-thinned, tapered web design reduces cutting resistance
• Bright uncoated finish for general-duty shop and field use
• Straight cylindrical shank fits standard keyed and keyless chucks

Compatibility

Designed as a standard jobber-length drill bit for use in any 3/8 inch or larger keyed or keyless drill chuck accepting a straight shank. Rated for primary use in steel and cast iron workpieces.

Installation Notes

Secure the shank fully in the chuck and confirm the bit runs true before drilling. Use cutting fluid or a suitable lubricant when drilling steel to extend tool life and manage heat. Right-hand rotation only — confirm spindle direction before engaging the workpiece. Follow applicable shop safety practices and wear appropriate eye protection whenever operating rotary cutting tools.
