Extra-Long Reach for Deep Holes

This 1/4 in. high-speed steel drill bit extends to 18 in. overall length with a 13 in. flute for deep drilling tasks. The straight round shank fits a wide variety of chucks and tool holders. It is sold individually for general-purpose work where extra reach is required.

Fits Standard Chucks, Reaches Tight Spaces

The straight shank design allows the bit to be held by common drill chucks and quick-change systems without special adapters. A 5 in. shank length provides secure grip while the long flute clears chips from deep holes. This design frees the user from needing specialised long-reach tooling for occasional deep drilling.

Steady Cutting in Steel and Wood

The 118° conventional point is designed to perform in a broad range of materials including iron, steel, wood and aluminium. High-speed steel construction resists heat buildup during sustained drilling in metal. The bit is not self-feeding, so steady pressure and speed control are needed for consistent results in deep holes.

Questions about this item

How deep can the 13 in. flute drill before I need to clear chips?

The flute runs 13 in., so that is the maximum continuous depth before you must withdraw the bit to clear swarf.

Will the straight 1/4 in. shank overheat or vibrate during all-day drilling in steel?

High-speed steel and a 118° point keep heat manageable; the round straight shank seats firmly in standard chucks, limiting run-out during extended use.

What chuck size must my drill already have to hold the 1/4 in. straight shank?

A 1/4 in. or larger three-jaw chuck is required; the straight shank fits any standard drill with that capacity.
