1/4 in Jobber Drill with Left-Hand Helix

This 1/4 in jobber-length drill bit features a left-hand helix designed for removing broken bolts or studs. The 118-degree conventional point starts cleanly in metal without walking. It is made from high-speed steel with a bright, uncoated finish and suits general-purpose drilling in ferrous and non-ferrous materials.

Decimal Equivalent .2500 and 118-Degree Point

The fractional 1/4 in size matches a decimal equivalent of .2500 for precise hole sizing. The 118-degree point angle handles mild steel, aluminium and plastic comfortably. Hardened tool steels or abrasive alloys will dull the uncoated high-speed steel cutting edges more quickly.

Bright High-Speed Steel Construction

The bright finish leaves the high-speed steel surface uncoated, allowing easy resharpening on a bench grinder. A straight shank fits standard three-jaw drill chucks and quick-change adapters without special tooling. No coolant-through holes are present, so external lubrication is required for deeper holes.

Questions about this item

Will the 1/4 in .2500 shank fit the 1/4 in chuck on my older drill press?

The shank is exactly .2500 in diameter, matching a standard 1/4 in chuck, so it seats without an adapter.

How do I confirm the 118 degree point is cutting correctly on first use?

The conventional point should produce clean chips and a round hole without walking; check chip shape and hole finish.

Does the 44416 jobber bit come with a case or lubricant, or must I buy those separately?

The bit is supplied alone; no case, coolant or lubricant is included, so purchase those separately if needed.
