Silver cylindrical carbide drill bit with two spiral flutes and a 118-degree four-facet point, 27/64 inch diameter

Cleveland

Cleveland C89610 27/64 in 118 Degree Carbide Drill Bit 1727

SKU CH-Y6SJ-AB9QW

A 27/64 inch carbide drill bit with a 118 degree point angle for general-purpose drilling

  • 27/64 inch diameter matches precise fractional sizing
  • 118 degree point angle centres quickly in metal
  • Solid carbide construction resists wear in hard materials
  • Bright uncoated finish allows easy inspection of cutting edges
  • Four facet point design improves chip evacuation

Cleveland C89610 Drill Bit

This Cleveland C89610 drill bit is a solid carbide twist drill built for precision holemaking in tough materials. It suits machinists and maintenance technicians who need a durable, jobber-length bit for general-purpose drilling.

118 Degree Four-Facet Point

The 118-degree four-facet point geometry centres the bit quickly and reduces walking on hard surfaces. Bright uncoated carbide resists wear without the added cost or thickness of a coating, and the non-coolant-through design keeps the tool simple for standard shop use.

27/64 Inch Fractional Size

The 27/64 inch diameter (decimal equivalent .4219) determines whether this bit matches the hole specification on your drawing. Buyers who need a different fractional size, a metric diameter, or a coolant-fed shank must select another tool.

Questions about this item

How often will the 118 degree 4-facet point on the 27/64 in carbide bit need resharpening?

The solid carbide construction holds its 118 degree 4-facet edge far longer than high-speed steel, so resharpening intervals are measured in hundreds of holes rather than dozens.

What stops me from drilling deeper with the 27/64 in jobber-length carbide bit in one go?

The jobber-length flute limits chip evacuation depth, so the practical limit is the flute length itself — deeper holes require peck drilling or a longer bit.

Does the bright uncoated 27/64 in carbide bit run hot enough to need coolant on long runs?

Carbide tolerates higher temperatures than steel, but the bright uncoated surface and zero coolant holes mean heat builds quickly; flood coolant or frequent pecking is advised for sustained use.
