Will it fit my torch?

YES! It fits all conventional torches.

What size holes will it cut?

As small as 2-1/2" out of base and up to 30" diameter. For larger diameter, buy the Chariot Cutting Guide (part number 24219).

There are two 25 lb. pull magnets.

YES. Part number 3311-EX (5 ft. circle).

The Flange Wizard 28439 Magnetic Circle Layout & Burning Guide will cut circles up to 30" in diameter.

Simply place the sharpened pin of the layout tool into your center punch mark and let the magnet slide down to sit firmly on the work surface.
The magnet is strong enough to support the weight of your torch, which frees your hands for more cutting control.
You can cut holes as small as 4" when you remove the base. Note: remove magnetic base when cutting small circles - heat can degrade magnetic strength.
NEW! A wheel has been added to the bushing for smooth and stable large circle cuts!
As a circle layout tool, the Magnetic Circle Layout & Burning Guide has a sliding soapstone holder and 360° scale on the magnetic base.
Layout bolt circles, mark for hole locations or baffle plate placement, circle sectioning or any number of reasons becomes a snap with Flange Wizard's layout scale and sliding soapstone holder.
