Value Collection 01247451 Jobber Drill 8.25mm Hss 118 Deg

Product Description

The VALUE COLLECTION 01247451 is a high speed steel (HSS) jobber-length drill bit designed for general-purpose drilling in steel, cast iron, and similar ferrous materials. Ground to an 8.25 mm (0.3248 inch) diameter with a standard 118-degree split point, this bit delivers consistent entry and reduced walking on flat or curved surfaces. An oxide coating provides moderate lubricity and surface hardness to extend tool life under normal shop or field conditions. Overall length is 4-39/64 inches (117 mm), with a 3-5/16 inch (84 mm) flute length. The straight cylindrical shank fits standard three-jaw drill chucks. Machinists, fabricators, pipefitters, and maintenance technicians are the typical users of this style of bit.

This jobber drill is suited for through-hole and blind-hole drilling operations in light to medium ferrous workpieces. Typical applications include structural steel fabrication, mechanical assembly, pipe and conduit preparation, and general maintenance drilling. The regular spiral flute and two-flute geometry promote chip evacuation in both hand-held and drill-press setups. The tapered web with web-thinning reduces thrust load when drilling by hand. It is sold and packaged as a single bit, making it a practical replacement or add-on to an existing set.

Key Features

• 8.25 mm (0.3248 inch) diameter fits within the 0.3000 to 0.3500 inch drill bit size range
• 118-degree standard point angle for general-purpose entry in ferrous materials
• High speed steel construction provides hardness and heat resistance during continuous drilling
• Oxide coating adds surface lubricity and corrosion resistance to extend bit life
• Web-thinned tapered web reduces drilling thrust and improves chip clearance
• Right-hand cutting, regular spiral flute geometry compatible with standard drill chucks

Compatibility

Designed for use in standard three-jaw drill chucks accepting a 0.3248 inch straight cylindrical shank. Primary workpiece materials listed by the manufacturer are steel and cast iron. Coolant-through drilling is not supported by this bit.

Installation Notes

Install the bit into a properly sized drill chuck and tighten securely before operation. Ensure the workpiece is clamped or fixtured to prevent rotation during drilling. Apply cutting fluid or lubricant when drilling steel to reduce heat buildup and extend bit life. Inspect the cutting edges for wear or chipping before each use and replace any bit that shows visible damage.
