Cle-Line

Cle-Line C22751 7/16" HSS Black/Gold 118° Jobber Drill Bit

SKU CH-X8HA-RA2SE

A 7/16 inch high-speed steel jobber drill bit with a 118-degree conventional point and black oxide finish

  • Product typeDrill Bits
  • High-speed steel construction resists wear during drilling
  • 118-degree conventional point starts holes cleanly in metal
  • Black oxide finish reduces friction and corrosion
  • 7/16 inch fractional size equals .4375 decimal equivalent
  • Jobber length provides standard reach for general use

Application & Audience

This Cle-Line jobber drill bit is made for general-purpose drilling in metal, wood and plastic. The 7/16 inch fractional size suits maintenance, fabrication and automotive tasks where a standard length is required. It is not for buyers who need coolant-through capability or a specialised point geometry for hardened alloys.

Upgrade Path

The black oxide finish on high-speed steel reduces friction and resists corrosion compared with uncoated bits. Moving to this bit is worthwhile when an older bit shows excessive wear, walking or discolouration from heat. It does not replace a cobalt or carbide tool for abrasive or high-temperature materials.

Sustained Use Behaviour

The conventional 118-degree point centres quickly and clears chips efficiently in typical jobber-length drilling. High-speed steel construction maintains hardness during repeated holes, while the black oxide surface helps retain lubricant. Performance remains consistent through a normal work session without the premium cost of coated or premium-alloy alternatives.

Questions about this item

What chuck size do I need for the 7/16 inch shank?

A 1/2 inch or larger three-jaw chuck is required to hold the .4375 inch shank securely.

How do I start the 118 degree conventional point without it wandering?

Centre-punch the workpiece, apply steady pressure, and begin at low RPM so the conventional point bites straight.

When should I replace this high-speed steel bit?

Replace it when the cutting lips are chipped, the black-oxide finish is worn off, or the bit no longer cuts cleanly at proper speeds.
