Drill America HSS annular cutter

Drill America DWC5-530-133 is a high-speed steel annular cutter built for fast, efficient hole making with a magnetic drill press. It cuts only the material needed to produce a quality hole and includes a pilot pin for accurate starts. The tool has a 3/4 inch Weldon shank that fits compatible magnetic drill presses.

For magnetic drill press operators only

This cutter suits users who work with a magnetic drill press and need a 1 inch diameter high-speed steel cutter for general purpose metal cutting. It is not for anyone who plans to use a standard hand drill, a conventional drill press or any machine without a 3/4 inch Weldon shank interface.

3/4 inch Weldon shank requirement

The single specification that decides fitment is the 3/4 inch Weldon shank, which only works with a magnetic drill press. If your equipment does not accept this shank, the cutter cannot be used and a different tooling interface is required.

Questions about this item

How do I fit the DWC5-530-133 annular cutter onto my magnetic drill press?

Slide the 3/4 inch Weldon shank into the press arbor until the flat seats, then tighten the grub screws; the step people miss is inserting the supplied pilot pin before locking the cutter.

What part of the DWC5-530-133 will need replacing first with regular use?

The pilot pin wears faster than the high-speed steel teeth, so keep spares and swap it when the tip rounds over or the cutter stops self-centring.

What limits how long I can run the DWC5-530-133 continuously in thick steel?

Heat builds in the high-speed steel body because the cutter only removes a thin ring of material; pause to let it cool and apply cutting fluid before the teeth lose hardness.
