Value Collection 01247907 Jobber Drill Bit 9.50mm Hss

Product Description

The VALUE COLLECTION 01247907 is a high speed steel (HSS) jobber-length drill bit ground to a 118-degree standard point angle with an oxide coating for improved lubricity and surface hardness. Measuring 5 inches overall length with a 3.625-inch flute length, this bit is sized at 9.50 mm (0.3740 inches) across both the cutting diameter and the straight cylindrical shank. The two-flute right-hand spiral design with a web-thinned, tapered web configuration reduces thrust at entry and promotes efficient chip evacuation. General-purpose grade HSS construction makes this a practical choice for machinists, maintenance technicians, and fabricators who need a reliable metric-size bit for everyday drilling operations.

This jobber drill bit is suited for drilling into steel and cast iron in production, maintenance, and repair environments. The straight shank fits standard three-jaw drill chucks on both bench-top drill presses and hand-held electric drills. The 9.50 mm diameter falls within the 9.00 mm to 10.00 mm size range, making it a common selection for through-hole and clearance-hole work in light fabrication, HVAC equipment assembly, and mechanical system installation where metric fastener clearances are required.

Key Features

• 9.50 mm (0.3740 inch) cutting diameter with matching straight cylindrical shank
• 118-degree standard point angle for general-purpose entry into steel and cast iron
• High speed steel construction with oxide finish for surface protection and reduced friction
• Web-thinned tapered web reduces cutting resistance and drill-press thrust load
• Two-flute regular spiral geometry promotes positive chip clearing
• 5-inch overall length with 3.625-inch flute length — standard jobber proportions for versatile reach

Compatibility

Designed as a general-purpose jobber drill bit compatible with any standard three-jaw drill chuck accepting a 0.3740-inch straight shank, including bench drill presses, magnetic drills, and hand-held electric drills used in metal fabrication and mechanical service work.

Installation Notes

Secure the shank fully in the drill chuck before operation and confirm the chuck is tightened at all three key positions to prevent slippage. When drilling steel or cast iron, use a center punch to locate the hole and apply a suitable cutting fluid to extend bit life and improve hole quality. Reduce feed pressure as the point breaks through to avoid grabbing. Inspect the cutting edges for wear before each use — a dull bit generates excess heat and can work-harden the workpiece surface.
