Value Collection BS2700021 Jobber Drill Bit 21/64 in Hss

Product Description

The VALUE COLLECTION BS2700021 is a high speed steel (HSS) jobber-length drill bit designed for general-purpose drilling in metal fabrication, maintenance, and light manufacturing environments. Ground to a 130-degree point angle with a web-thinned, tapered web configuration, it delivers clean entry and reduced thrust on start-up. The 21/64 inch (0.3281 inch decimal) diameter and slow spiral flute geometry make it well suited for softer materials where chip evacuation and hole finish matter. Right-hand cutting direction follows standard drill press and handheld drill convention. This bit is sold individually and is appropriate for use by machinists, maintenance technicians, pipefitters, and general tradespeople who need a reliable fractional-size drill on the bench.

The BS2700021 is intended for drilling aluminum, copper, brass, and other non-ferrous materials where a slow spiral flute controls chip flow without work-hardening the workpiece. Its 4-5/8 inch overall length falls within the standard jobber range, making it compatible with most 3-jaw drill chucks on benchtop drill presses, hand drills, and drill motors. The straight cylindrical shank fits standard keyless and keyed chucks. It carries an ANSI specification designation, confirming it meets dimensional standards expected in trade and light industrial settings.

Key Features

• 21/64 inch diameter (0.3281 inch decimal) for fractional-size hole requirements
• 130-degree point angle reduces walking and improves self-centering on entry
• Web-thinned tapered web lowers thrust force and eases hand-drill use
• Slow spiral flute geometry optimized for aluminum and non-ferrous workpiece materials
• High speed steel construction with bright/uncoated finish for general-purpose applications
• Straight cylindrical shank fits standard keyed and keyless drill chucks

Compatibility

Designed as a general-purpose jobber drill bit for use in standard drill presses, hand drills, and drill motors equipped with chucks sized to accept a straight cylindrical shank. Optimized for aluminum and non-ferrous workpiece materials per ANSI specification designation.

Installation Notes

Installation is performed by machinists, maintenance technicians, or tradespeople using standard drill equipment. Secure the straight shank firmly in a keyed or keyless chuck before operation, and verify the workpiece is clamped or fixtured to prevent movement. Power down and de-energize any drill press or pneumatic drill motor before changing bits. Cutting fluid or light oil is recommended when drilling non-ferrous metals to extend tool life and improve hole finish, though coolant-through capability is not available on this bit.
