SKU CH-VPX9-Y43JH

  • Extra length reaches deep holes with the 12 inch shaft
  • 135 degree point angle and four cutting edges prevent walking
  • Black oxide tempering reduces friction and improves chip flow
  • High speed steel construction handles wood plastic wallboard plywood and soft metals
  • Suitable for occasional stainless steel and hard metal drilling

Product Identity

The Disston Company 504696 is a 12-inch extra-length drill bit made from high-speed steel with a black oxide finish. It targets tradespeople and DIY users who need extended reach for wood, plastic, wallboard, plywood and soft metals such as aluminium, brass and bronze.

Installation Notes

The 135-degree point angle with four cutting edges eliminates walking and allows fast penetration without a centre punch. Black oxide tempering reduces friction and improves chip flow, so the bit clears debris efficiently during deep holes. No special tools are required beyond a standard drill chuck that accepts a 3/8-inch shank.

Suitability

This bit suits occasional drilling in stainless steel and other hard metals, but it is not intended for continuous heavy-duty work in those materials. Buyers who need a shorter bit for general-purpose drilling or a dedicated cobalt or carbide tool for frequent hard-metal applications should look elsewhere.

Questions about this item

How can I confirm the 135-degree point with four cutting edges is drilling straight without walking?

The 135-degree split point with four cutting edges self-centres on contact; watch for immediate bite and a centred hole with no skidding across wood, plastic, wallboard, plywood, aluminium, brass or bronze.

Does the carded pack contain only the 12-inch, 3/8-inch high-speed steel bit or are there additional accessories?

The carded package includes the single 12-inch, 3/8-inch high-speed steel drill bit with black oxide finish; no extra bits, pilot drills or adapters are supplied.

Should I choose the 504696 extra-length bit or a shorter version for drilling soft metals and occasional stainless steel?

Select the 504696 12-inch extra-length bit when you need the reach for deep holes in wood, plastic, wallboard, plywood, aluminium, brass, bronze or occasional stainless steel; a shorter bit is better for shallow work.
