Chicago-Latrobe 78484 118° Carbide Spade Drill
This solid carbide spade drill bit is built for precision drilling in demanding machining applications. Its 118-degree point angle and bright uncoated finish suit machinists and fabricators who need clean holes in hard materials. The fractional 1/8-inch size with a 0.1250 decimal equivalent fits standard tooling setups. It is sold new and ready for immediate workshop use.
Fits standard drill chucks
The straight shank design allows direct clamping in common drill chucks, collets or CNC tool holders. No special holders or bushings are required, freeing up tool crib space and reducing changeover time. The solid carbide construction resists wear in abrasive alloys, extending intervals between tool changes. Bright finish aids chip evacuation in deep-hole work.
Uncoated bright finish eliminates coating
Without a coating layer there is no risk of delamination when the bit encounters interrupted cuts or high thermal cycling. This makes the tool predictable in materials where coated drills can chip at the coating interface. The 118-degree point is a general-purpose geometry that does not require specialised regrind fixtures. Orders of $75 or more ship free from the supplier.

Questions about this item
What diameter hole does the 0.1250-inch drill produce?
The drill creates a 0.1250-inch diameter hole, matching its 1/8-inch fractional size.
How hot does the solid carbide bit get during continuous drilling?
Solid carbide handles high heat well, but the bright uncoated finish offers no thermal barrier, so the bit will become very hot under sustained use.
What shank style fits this 78484 spade drill?
The 1/8-inch solid carbide spade drill uses a straight shank that fits standard drill chucks or collets.
