Precision Twist Drill 6000298 Taper Length Drill Bit

Product Description

The PRECISION TWIST DRILL 6000298 is a taper length high speed steel drill bit designed for general-purpose drilling across a wide range of metallic and non-metallic materials. It features a 0.2810 inch (9/32 inch) diameter, a 118-degree standard point angle, and a bright/uncoated finish. The spiral flute design and right-hand cut deliver consistent chip evacuation and clean entry in production and maintenance drilling applications. The straight shank and web-thinned, tapered web configuration reduce thrust requirements and improve hole quality. This bit is part of the Series R55 line and conforms to ANSI standards.

This drill bit is suited for use in machine shop, fabrication, HVAC rough-in, plumbing, and general mechanical trade applications where a longer flute length is needed to reach deeper hole depths or to drill through thicker stock. It is appropriate for use with drill presses, lathes, and handheld power drills. Compatible materials include alloy steel, aluminum, aluminum alloy, brass, bronze, carbon steel, cast iron, copper, graphite, hardened steel, high strength bronze, magnesium, magnesium alloy, malleable iron, nickel, nickel alloy, reinforced plastic materials, stainless steel, and cermet.

Key Features

• 0.2810 inch (9/32 inch) diameter with straight shank of equal diameter for secure chuck engagement
• 118-degree standard point angle with web-thinned, tapered web for reduced thrust and easier starting
• 3-7/8 inch flute length provides a 6xD flute-to-diameter ratio for deeper reach than jobber-length bits
• 6-1/4 inch overall length suits taper-length drilling applications in tighter or deeper setups
• High speed steel construction handles a broad range of ferrous and non-ferrous materials
• Bright/uncoated finish, right-hand spiral flute, ANSI-conforming Series R55

Compatibility

Designed as a general-purpose taper length drill bit for use with standard 3-jaw chucks accepting straight shanks up to 9/32 inch. Suitable for drilling alloy steel, aluminum, brass, bronze, carbon steel, cast iron, copper, hardened steel, stainless steel, magnesium, nickel, malleable iron, cermet, graphite, and reinforced plastic materials.

Installation Notes

Install into a properly sized chuck and verify shank is fully seated and tightened before operation. Power down or de-energize the drill press or machine before changing bits. Use appropriate cutting fluid or coolant for ferrous and stainless steel applications to extend bit life, noting this bit does not have coolant-through capability. Follow applicable shop safety practices and machine guarding requirements during use.
