Value Collection 01188408 No. 40 Hss Jobber Drill Bit

Product Description

The VALUE COLLECTION 01188408 is a No. 40 wire-size jobber-length drill bit ground from high speed steel (HSS) with a black oxide finish. It produces a 0.098-inch diameter hole using a standard 118-degree split-point geometry and a regular spiral flute with a tapered, web-thinned web configuration. At 2.375 inches overall length with a 1.375-inch flute length, this is a compact, general-purpose bit suited for drilling ferrous metals including steel and cast iron. It is a right-hand cutting, straight-shank tool installed in standard drill chucks by machinists, maintenance mechanics, metalworkers, and field tradespeople.

This bit is rated for general-purpose drilling in steel and cast iron and fits the 0.050-to-0.100-inch decimal-inch drill bit size range. It is well suited for bench drill presses, hand drills, and drill-press fixtures used in light fabrication, maintenance, and repair work. The straight cylindrical shank seats in any standard Jacobs-style or keyless chuck. Typical applications include pilot holes, through-hole drilling in sheet metal, and clearance holes for fasteners in ferrous materials.

Key Features

• No. 40 wire size, 0.098-inch diameter for precise small-diameter hole work
• 118-degree standard point angle with web thinning reduces entry force and walking on ferrous materials
• High speed steel construction provides heat resistance during dry cutting
• Black oxide coating improves lubricity and provides light corrosion protection
• Regular spiral flute with tapered web configuration promotes chip evacuation in steel and cast iron
• Right-hand cut, straight cylindrical shank fits standard drill chucks without adapters

Compatibility

Designed as a general-purpose jobber drill bit for drilling steel and cast iron; fits any drill press, hand drill, or machining center equipped with a standard chuck capable of holding a 0.098-inch straight shank.

Installation Notes

Installation and use should follow standard machining and drilling safety practices. Secure the workpiece with appropriate clamping before drilling to prevent rotation. Use cutting fluid or cutting oil when drilling steel to extend bit life and improve hole quality. Inspect the bit for wear or chipping before each use, as small-diameter HSS bits are susceptible to breakage under side load or excessive feed pressure.
