Extension Drill Bit for Deep Reach

The Cleveland C13200 is a 12 inch aircraft extension drill bit made from high speed steel. Its 7/16 inch diameter and 135 degree split point suit precision drilling in deep or confined workpieces. Machinists and maintenance technicians use it where standard length bits cannot reach.

Sustained Cutting in Hard Materials

The high speed steel body maintains hardness at the elevated temperatures produced during extended drilling cycles. A 135 degree split point reduces thrust force and prevents walking, so the bit stays on centre through the full 1 3/4 inch maximum drilling depth. The 21 to 34 degree helix range supports consistent chip evacuation in tough alloys.

Replaces Standard Length Bits for 4xD Holes

This bit upgrades from jobber length drills when hole depth reaches four times the diameter. The 12 inch overall length bridges the gap without the runout of a separate extension holder. It is not for hand held drilling where rigidity is low or for diameters outside the 7/16 inch fractional size.

Questions about this item

How much heat builds up in the 135-degree split-point tip during continuous drilling?

The 135-degree split-point geometry on the high-speed-steel bit reduces thrust and friction, so the tip runs cooler than a standard point when drilling to the full 1 3/4-inch depth.

What shank size must my drill chuck accept for the 7/16-inch bit to fit?

The bit has a 7/16-inch shank, so your drill chuck must open to at least 7/16 inch to hold it securely.

Will the 12-inch overall length reach through the workpiece on my older drill press?

At 12 inches long the bit provides extra reach, but the maximum drilling depth is 1 3/4 inches, so the workpiece thickness must stay within that limit regardless of the machine.
