Value Collection 81430084 Jobber Drill Bit 1/8 in Hss

Product Description

The VALUE COLLECTION 81430084 is a 1/8-inch high speed steel (HSS) jobber-length drill bit designed for production and maintenance drilling in metal fabrication and general trade applications. The bit features a 135-degree split point that reduces walking and allows drilling to start without a center punch in most setups. A parabolic flute geometry improves chip evacuation during deeper cuts, reducing heat buildup and the need for repeated pecking cycles. At 2.75 inches overall length with a 1.625-inch flute length, this is a standard jobber reach suitable for the majority of through-hole and blind-hole drilling operations in steel and cast iron workpieces.

This drill bit is intended for use in handheld electric drills, drill presses, and CNC machining centers where a straight cylindrical shank is compatible with the chuck or collet in use. Primary workpiece materials include steel and cast iron. The bright uncoated finish makes it a cost-effective choice for general-purpose drilling where coated tooling is not required. It is well suited for HVAC, plumbing, electrical, and mechanical trade applications involving ferrous metal drilling on the job site or in a shop environment.

Key Features

• 135-degree split point reduces walking and eliminates the need for center punching in most applications
• Parabolic flute design promotes efficient chip removal and reduces heat buildup in deeper holes
• Heavy duty HSS construction provides durability in ferrous metal drilling including steel and cast iron
• Web-thinned tapered web lowers cutting resistance and improves penetration rate
• Bright uncoated finish suitable for general-purpose applications without added coating cost
• Straight cylindrical shank compatible with standard 3-jaw chucks and collets

Compatibility

Designed as a general-purpose jobber drill bit for use in standard drill presses, handheld electric drills, and CNC machining centers equipped with a 1/8-inch capable straight-shank chuck or collet. Primary workpiece materials are steel and cast iron.

Installation Notes

Installation should be performed by machinists, tool and die technicians, or qualified trade professionals familiar with rotating cutting tool safety. Secure the shank fully into the chuck or collet before applying power, and verify runout is within acceptable limits before beginning a cut. Use appropriate cutting fluid or coolant for steel workpieces to extend tool life, noting that this bit does not support coolant-through delivery. Always wear appropriate eye protection and follow applicable OSHA standards for rotating machinery.
