Packaging

Every tool is packed on its own: a tip cap protects the cutting edge, and each shank tool sits in its own reusable tube, sized to the shank and length and labelled for your order.
Micro tools (drills and end mills below about Φ3) go in micro tubes that hold the tool without touching the edge.
Inserts and crown drill tips are packed in slotted insert boxes, 10 per box for standard inserts.
Tubes are grouped in 5- or 10-piece boxes, then packed in export cartons sized to the order; reinforced or palletised packing for sea freight on request.
