Like all of our cutters, PreciseBIT PCB drills are  made using the finest grade Mitsubishi carbide. Sizes ranging from 0.008 in. (0.2mm) to 0.250 in. (6.35mm) are available from stock. Diameters down to 0.001 in. (25 micron) are available upon request. Slotting drills and high aspect ratio tools are available on a special order basis.

Our 6-flute PreciseBIT contour routers have been optimized for machining FR-4 epoxy/glass, phenolic paper, polyamide, and other common PCB substrates.  3-flute, high aspect ratio tools are available for machining more exotic substrates.

Diamond cut

Designed by a corrosion chemist to:

• dissolve varnish and gummy deposits in the spindle bore
• loosen rust
• inhibit corrosion

in spindle bores and on collets and toolholders.

True spiral 2-flute "V" point mechanical etching bits offer an optimum combination of high resolution cutting and tip strength. The plunge style tip geometry insures reliable copper removal at all isolation widths. Both coated and uncoated bits are available from stock.  Compatible with AccurateCNC, LPKF, T-Tech and MITS, desktop PCB prototyping machines.

Our 2-flute stub end-mills are characterized by low aspect ratio flute geometries insuring low deflection and long bit life at relatively high feed-rates. The precise radial relief reduces burr formation and chattering resulting in smoother, more uniform cutting. Some of the larger diameter stubs are offered with a "rubout" tip that eliminates residual copper dots when "plunge etching" small areas of copperclad

Scoring/Engraving Countersinks

Unlike conventional countersinks, which are designed solely for plunge cutting, the EM4E8 family of Scoring/Engraving tools can also be used for sign carving, beveling, scoring and engraving.
