Chicago-Latrobe 78488 Spade Drill
The Chicago-Latrobe 78488 is a solid carbide spade drill bit with a 118-degree point angle. It features a bright, uncoated finish and a decimal equivalent of .2500. This power tool accessory is designed for precision drilling applications.
Suited for machinists needing uncoated carbide
This drill suits machinists who require a solid carbide spade drill with a standard 118-degree point for general-purpose work. It is not intended for buyers who need a coated cutting tool for extended wear resistance. Users requiring a different drill point geometry or shank style should look at alternative options.
Solid carbide construction maintains rigidity
The solid carbide body provides high rigidity during sustained drilling operations, resisting deflection better than steel alternatives. The bright finish allows for easy visual inspection of the cutting edges. The 118-degree point angle centres the drill quickly to maintain accuracy throughout the cut.
Highlights
- Solid carbide construction resists wear
- 118-degree point angle centres accurately

Questions about this item
What size drill chuck is needed to hold the 0.2500 in shank?
A chuck that opens to at least 1/4 in (0.2500 in) will grip the solid carbide shank securely.
Will the 118 degree point angle cut cleanly in the mild steel I usually drill with older high-speed bits?
Yes, the 118° point is a general-purpose angle that works well in mild steel, though carbide stays sharp longer than high-speed steel.
How can I confirm the bit is running true after I clamp it in the drill press?
Watch the tip at low speed; a true-running carbide spade drill shows no visible wobble at the 0.2500 in diameter.
