SKU CH-21VG-C4Y62

Solid carbide straight-flute drill with a 140-degree point cuts 13/64 inch holes in hardened materials

  • Product typeCutting Tools
  • 13/64 in diameter drills precise fractional holes
  • 140-degree point angle reduces walking on hard surfaces
  • Solid carbide construction resists wear in abrasive materials
  • Straight flute design clears chips efficiently in shallow cuts
  • Bright uncoated finish suits non-ferrous and general-purpose drilling

Chicago-Latrobe 78597 13/64 in Carbide Drill

This Chicago-Latrobe 78597 is a straight-flute drill bit made from solid carbide for machining applications. The fractional 13/64 inch size equals 0.203125 inch and the flute length measures 1 3/16 inches. It is designed for precision drilling in hard materials.

Machinists needing 140-degree point

The 140-degree four-facet point angle and uncoated bright finish suit operators drilling tough alloys where a rigid carbide tool is required. Builders who need coated bits, different point angles or non-carbide substrates should look at other options.

13/64 inch fractional size with 140-degree point

The single specification that decides fit is the 13/64 inch diameter combined with a 140-degree point angle. Confirm this exact fractional size and point geometry match the hole specification before ordering.

Questions about this item

How can I confirm the 140 degree point angle is cutting correctly after setup?

Check for clean, centred holes at the 0.203125 decimal size with minimal wander and consistent chip formation across the 1 3/16 in flute length.

What comes in the box and what must I buy separately for the 78597 drill?

The box contains the solid carbide straight flute drill bit only; a compatible drill chuck or collet for 13/64 in shanks and cutting fluid are purchased separately.

When should I choose the 13/64 in size over other fractional options?

Select the 13/64 in bit when the hole specification calls for the 0.203125 decimal equivalent and the material requires the rigidity of solid carbide.
