Chicago-Latrobe 52473 Drill Bit

The Chicago-Latrobe 52473 is a Silver & Deming drill bit designed for general-purpose drilling tasks. It features a 118-degree point angle suitable for a wide range of materials. The bit is constructed from high-speed steel with a black oxide finish for durability. Its 1/2 reduced shank allows compatibility with standard drill chucks.

Upgrade From Smaller Capacity Bits

This bit replaces smaller diameter twist drills when a larger hole size is required beyond standard chuck capacity. The jump is worth it when the application demands a 1 9/64 inch hole without changing to a specialty tool. The reduced shank bridges the gap between large diameter needs and common drill chucks. High-speed steel construction handles the increased cutting forces involved.

Suited For General Machining And Maintenance

This drill bit suits machinists and maintenance technicians drilling large holes in metal using standard equipment. The black oxide finish aids chip flow and resists corrosion during repetitive use. Buyers who need carbide-tipped cutting edges for abrasive materials should look elsewhere. Users requiring a split-point design for self-centering on hard surfaces should consider other options.

Questions about this item

What size chuck does the 1/2 reduced shank on the 52473 drill bit fit?

The 1/2 reduced shank fits a standard 1/2 inch drill chuck, allowing use with drills that cannot accept a full 1 9/64 inch shank.

How do I prevent the 118 degree point from walking when starting a hole in steel?

Use a centre punch to mark the exact centre, then apply steady pressure at low RPM with cutting fluid to keep the 118 degree point engaged.

When should I replace this high speed steel bit instead of resharpening it?

Replace the bit if the black oxide finish is worn through, the cutting lips are chipped, or the 118 degree point angle cannot be restored accurately.
