Drill Bit for Deming Applications

The Chicago-Latrobe 55482 is a Silver & Deming drill bit designed for creating large-diameter holes in metalworking tasks. Its 118-degree point angle suits general-purpose drilling in steel and other ferrous materials. The black oxide finish adds wear resistance during extended use. This new accessory targets machinists and maintenance crews needing reliable hole enlargement.

Half-Inch Shank Fits Standard Chucks

A reduced 1/2-inch shank allows the bit to seat securely in common drill presses and heavy-duty hand drills without requiring a larger chuck. The High-Speed Steel construction maintains hardness at elevated temperatures generated by deep cuts. This configuration frees the operator from sourcing specialised large-capacity holders for occasional oversize holes.

Sustained Cutting in Tough Alloys

Machining High Speed Steel retains edge integrity when feed pressure and spindle speed are held steady through thick workpieces. The 118-degree geometry distributes cutting forces evenly to reduce chatter during long drilling cycles. Heat buildup is managed by the material composition rather than external coatings alone. Operators who need aggressive feed rates in abrasive alloys should verify coolant strategy separately.

Questions about this item

How does the 118-degree point angle affect drilling in harder metals?

The 118-degree point is a general-purpose geometry that centres quickly in mild steel and aluminium but generates more thrust force in hardened alloys, so cutting speed drops sooner under sustained pressure.

Does the black-oxide finish help the bit run cooler during extended use?

Black oxide retains some lubricity and reduces galling, yet the bit still relies on external cutting fluid and proper feed rate to manage heat during all-day drilling.

Will the 1/2-inch reduced shank fit my drill press without an adapter?

Yes, the shank is turned down to 1/2 inch so it clamps directly in any standard 1/2-inch chuck on a drill press or heavy-duty hand drill.
