Chicago-Latrobe 78489 Spade Drill Bit

The Chicago-Latrobe 78489 is a solid carbide spade drill bit built for machining hard materials. It targets professionals and workshops that need a rigid, wear-resistant cutter for precise holemaking in tough alloys.

Upgrading from high-speed steel or coated bits

Switching to this carbide bit makes sense when high-speed steel edges dull too quickly or when workpiece hardness demands the stiffness of solid carbide. The jump pays off in longer tool life and consistent hole quality on abrasive or hardened stock.

9/32 inch diameter with 0.2813 shank and 2.5 length

The 118-degree point and bright finish handle general-purpose drilling in steel, cast iron and non-ferrous metals with good chip evacuation. The solid carbide body resists deflection in deeper cuts, though the fixed 2.5-inch overall length limits reach in deep-hole applications.

Questions about this item

What shank diameter does the 78489 spade drill bit need for the chuck?

The bit has a 0.2813 in shank, so the chuck must accept that exact diameter.

How should the 118 degree point angle be aligned when starting a hole?

Keep the drill perpendicular to the workpiece so both cutting lips engage simultaneously; tilting causes the point to walk.

When does the solid carbide 9/32 in bit need replacement?

Replace it when the cutting edges dull enough to increase feed force or produce rough holes; carbide cannot be resharpened easily.
