Value Collection BS27N0043 No. 43 Hss Jobber Drill Bit

Product Description

The VALUE COLLECTION BS27N0043 is a No. 43 wire-size jobber-length drill bit designed for general-purpose drilling in aluminum and other non-ferrous materials. Ground from high-speed steel (HSS) with a bright, uncoated finish, it measures 0.0890 inches in diameter and 2.25 inches overall. The 130-degree split point with web thinning helps the bit start on contact and reduces walking on smooth surfaces. A slow-spiral flute geometry moves chips efficiently when working softer metals, reducing clogging and heat buildup. Right-hand cutting direction follows standard CW rotation on conventional drill presses and hand drills.

This bit is suited for light metalworking, sheet-metal layout, and small-diameter through-hole work in aluminum, brass, copper, and similar non-ferrous stock. Machinists, maintenance technicians, HVAC fabricators, and electricians reach for wire-gauge bits when working with thin-wall tubing, electrical enclosures, and sheet goods where precision hole diameter matters. The No. 43 size is a common choice for tapping and clearance holes in fine-thread applications.

Key Features

• No. 43 wire gauge size — 0.0890 inches diameter for close-tolerance hole placement
• 130-degree point angle with web thinning for self-starting penetration and reduced thrust
• Slow-spiral flute design optimized for aluminum and non-ferrous chip evacuation
• High-speed steel construction provides adequate hardness for repeated general-purpose use
• Bright, uncoated finish — no coating to chip or peel during regrinding
• Straight cylindrical shank fits standard 3-jaw drill chucks without adapters

Compatibility

Designed as a general-purpose jobber drill bit for use in aluminum and non-ferrous materials, compatible with any standard drill press or hand drill accepting a straight-shank bit at 0.0890 inches diameter. Conforms to ANSI specification designation for jobber-length drill bits.

Installation Notes

Secure the workpiece firmly before drilling to prevent rotation or movement. Ensure the drill chuck is fully tightened around the straight shank before starting the spindle. For best results in aluminum and non-ferrous stock, use a cutting fluid or light oil to extend bit life and improve hole finish. Inspect the cutting edges before each use and remove the bit from service if chipping or dullness is visible.
