Westward 5VPA9 5/16" Carbide Jobber Drill Bit

SKU CH-8J8W-F5PKV

A 5/16 inch carbide jobber drill bit with a black and gold finish and 118 degree point angle

  • Product typeAngle, Pitch & Slope Locators
  • 5/16" drill size suits common fastening tasks
  • 118-degree point angle centres quickly in metal
  • Carbide construction resists wear in abrasive materials
  • Bright uncoated finish allows easy resharpening
  • Jobber length gives standard reach for general drilling

Precision drilling in hardened materials

The Westward 5VPA9 is a 5/16 inch carbide jobber drill bit built for workshops that need reliable hole-making in tough metals. Its 118 degree conventional point starts cleanly without a pilot hole. The bright uncoated surface suits general-purpose machining where coating buildup is unwanted. Decimal equivalent .3125 matches standard fractional sizing.

Fits standard drill chucks and collets

The straight shank seats in any three-jaw chuck or ER collet sized for 5/16 inch tooling. Jobber length provides enough flute reach for through-holes in plate and bar stock without excessive overhang. Carbide construction resists wear in abrasive alloys that would dull high-speed steel quickly. Non-coolant-through design means external flood or mist cooling must be supplied by the machine.

No bundled accessories or software included

The bit ships as a single cutting tool ready for immediate use. No driver, case, or lubricant is packaged with it. Operators supply their own coolant strategy and tool-holding hardware. This keeps the purchase focused on the carbide substrate and geometry that determine tool life.

Questions about this item

Will the 118-degree point angle limit how deep I can drill in steel without re-sharpening?

The 118-degree conventional point is a general-purpose geometry; it centres well in mild steel but can walk or dull faster in hardened alloys, so frequent touch-ups may be needed on deep holes.

Does the carbide body run hot enough to burn fingers during a full day of repetitive drilling?

Carbide conducts heat differently than high-speed steel; the bit will get hot during sustained use, so allow cooling periods and use cutting fluid to manage temperature.

Do I need a 1/2-inch chuck to hold the 5/16-inch shank on this jobber-length bit?

The shank matches the 5/16-inch drill diameter, so any chuck that opens to at least .3125 in will hold it; a 3/8-inch or larger chuck is sufficient.
