20PC Double Cut Carbide Burr Set, 0.118 inch (3 mm) Heads
Twenty 3 mm double-cut heads in a display rack – a complete micro-size programme for detail and small-part work.
Design and Construction
Twenty 3 mm (0.118″) double-cut heads in a clear display rack, covering every small-head geometry from cylinder to flame. The rack stands on the bench and shows the whole programme at a glance.
How It Works
Small heads run at the top of the speed range – about 30,000-65,000 RPM for the 3 mm class – giving controlled detail work with minimal removal per pass.
Applications
Detail deburring, small-part machining support, model and jewellery work, electronics enclosures.
Field Cases
- Electronics assembly: 3 mm heads deburred enclosure slots without panel distortion.
- Model engineering: the rack covered every port and channel on a small engine.
