offers two families of precision cutters, PreciseBITs and
UltraBITs. These tools range in
size from 0.005 in. (0.125 mm) to 0.2500 in. (6.35 mm). All PreciseBits bits are made of premium grade Sandvik and
Mitsubishi submicrograin tungsten carbides.
A variety of tip styles are available, including:
ball-nose, fish tail, "V" tip,
and drill point. Certified for use
at 20k-100k RPM, these tools run in most CNC environments.
All of our bits are made in the USA.
from both families are available for soft
media (hardwoods, softwood, polymers, ivory, horn, and resin stabilized
wood), composites (paper phenolic,
fiberglass, carbon fiber, turquoise, malachite, and Micarta) and non-ferrous
metals (aluminum, brass, copper, gold, silver, sterling, and platinum).
PreciseBITs - the standard in wood and
These two fluted micro-tools have a long track record of superb
performance across a variety of applications. PreciseBITs
are designed for use in applications that demand moderate to high precision.
The optimized flute geometry and high flute volume combined with a radical
fish-tail point result in tools that are aggressive in both milling and drilling
operations. Suitable materials include hardwoods, softwoods, cast
thermoplastics, turquoise, malachite, ivory (2 flute only) and selected
UltraBITS - custom tools at stock prices
Our new family of tools was developed in response to
the growing need for greater precision by cuemakers, steel rule die makers,
luthiers and clockmakers. Comprising
both 2 , 3 and 5 flute designs, UltraBITs are laser and/or optically inspected
to insure compliance with the tighter tolerances (+/-0.0005 in.) demanded by
these applications. Each new design
is tested for performance in particular applications before release, leading to
our designation of UltraBITs as the first truly "application
specific micro-tools" available to the woodworking industry.
application specific tool concept was initially developed at the request of cuemakers and luthiers to
support the growing use of "zero-glue-line" inlay, a form of marquetry where
the pocket and the component are so closely matched that there is virtually no
visible glue line after assembly. The 3 flute design offers superior rigidity
and chatter-free cutting. Radially relieved, high rake cutting edges combine
aggressive cutting action with long tool life. The bits are intended for
machining hardwoods, cast thermoplastics, turquoise, malachite and most
composites. A special high-volume 2
flute design has been optimized for precision machining of ivory and materials
that tend to cake and/or expand during cutting.
