Cutting Bits
The CarveWright comes equipped with two bits mounted in bit adapters.
These are the 1/16” tip diameter carving bit and a 1/8” cut-off bit.
Additional bits and bit adapters, made to the CarveWright specifications,
are available through the CarveWright web site.
WARNING: Piloted bits can NOT be used in the machine
machine even if the pilot bearings have been removed..
WARNING: Use only CarveWright branded bits with the
machine. The machine is calibrated to work with bits within
certain specifications, and if these specifications are not met
the results can be undesirable. It is possible to overstress the
machine with nonstandard bits, which could be both damaging
to the machine and hazardous.
Bit Adapter Assembly
The CarveWright utilizes a patented quick release chuck system to make
changing bits fast and easy. To use this system the bits must first be
installed into the bit adapters. We recommend that each 1/4" bit used in
the machine have its own dedicated adapter since the setscrews are
required to be thread cemented. Swapping adapters will lead to stripped
setscrews. In the case that the bit needs to be replaced, apply heat to the
setscrews first to soften the thread cement before loosening. The bits
must be spaced properly in the adapters. Please see Figure 31 and 32 for
proper spacing.
For 1/2” shank bits, insert threaded bit adapter into the chuck assembly
and then insert bit into threaded collet (See Figure 29) and tighten the
collet with a wrench. Position the bit in the adapter as shown in Figure 31.
Verify that the collet is also securely tightened.
For 1/4” steel shank bits: Remove the two setscrews from the adapter
body and de-grease both the setscrews and threaded holes. This can be
done using rubbing alcohol or a product such as WD40. Thoroughly dry
the parts. Apply a drop of permanent thread cement on each setscrew to
prevent them from loosening and start the treads. Insert the bit into the bit
adapter and tighten the setscrews with supplied Allen wrench (See Figure
30). Position the bit in the adapter as shown in Figure 31 and always
make sure the setscrews are tight.
For 1/4” carbide shank bits: Carbide bits include the 1/16” carving and
1/8” cutting bits and can be identified by the two small flats on the bit
