Value Collection 01247121 Jobber Drill Bit 7.30mm Hss

Product Description

The VALUE COLLECTION 01247121 is a high speed steel (HSS) jobber-length drill bit ground to a 118-degree standard point angle and finished with an oxide coating for basic corrosion resistance. At 7.30 mm (0.2874 inches) in diameter with a 4.25-inch overall length, this bit covers the most common mid-range hole sizes encountered in general-purpose metalworking and fabrication. The web-thinned, tapered-web geometry reduces thrust load at the point and improves chip clearance through the two regular spiral flutes. The straight cylindrical shank seats securely in standard three-jaw chucks. This is a right-hand cutting bit suited for drill presses, hand drills, and mill setups used by machinists, pipefitters, electricians, and HVAC technicians.

This drill bit is designed for general-purpose drilling in steel and cast iron workpieces. It fits typical production and service applications where a reliable, consumable bit is needed without the cost of coated premium grades. The 2.9531-inch flute length provides adequate chip evacuation for through-hole work in material thicknesses commonly encountered in sheet metal, structural steel, and pipe fabrication. It is sold individually, making it a practical replacement or spot addition to an existing drill index.

Key Features

• 7.30 mm (0.2874 inch) diameter covers the 0.2500 to 0.3000 inch jobber size range
• 118-degree standard point angle with web-thinned, tapered-web construction reduces entry thrust
• High speed steel construction with oxide finish for general-purpose durability
• Regular spiral, two-flute design with 2.9531-inch flute length for consistent chip clearing
• Straight cylindrical shank compatible with standard drill chucks
• Right-hand cutting direction for use with conventional drill presses and hand tools

Compatibility

Designed as a general-purpose replacement or stock jobber drill bit for use in standard three-jaw chucks accepting a 0.2874-inch straight shank; suitable for drilling steel and cast iron in typical trade and shop applications.

Installation Notes

Secure the shank fully in the chuck and verify runout before drilling. Always reduce feed rate when breaking through the back side of the workpiece to prevent bit grab. Use appropriate cutting fluid when drilling steel to extend bit life and reduce heat buildup. Wear eye protection and ensure the workpiece is clamped or fixtured before starting the cut.
