01DRILL & SCREWDRIVER ACCESSORIES
Precision in a spherical point
A set of five spherical burrs rests quietly in the workshop drawer, each head a tiny globe of abrasive grit waiting to touch the workpiece. The black finish suggests a tool that has already seen heavy use, yet remains sharp and ready for the next cut.
These bits are designed for the craftsman who works with hard materials like glass, tile, jade and hardened metals. They suit tasks ranging from delicate engraving to broader filing and drilling, offering a consistent point of contact for rotary tools.
02MATERIALS
Electroplated diamond on a steel core
The working face is coated with electroplated diamond grit, providing a coarse abrasive surface suitable for tough substrates. This construction allows the bit to bite into glass, stone and metal without wearing down quickly, maintaining its spherical geometry through repeated passes.
04APPLICATION
For carving, drilling and filing
The spherical profile makes these bits versatile for multiple operations. They are effective for forming shapes, removing material and creating smooth curves in molds or instruments. The coarse 40-grit rating indicates they are intended for initial shaping and correction rather than final polishing.
COMPATIBILITY
Fits various rotary power tools
Designed to mount in hanging mills, electric mills and general engraving machines, the standard shank size ensures broad usability. The compact package measures 11 x 22 x 33 cm, keeping the five pieces organised and protected during storage or transport to the workbench.
