Ø 10,0 x 88 mm. NEXT GENERATION – Extra stable special drill for hard requirements on hand drills. Good suited for clean and burr-free milling of welding spots and thin-walled work pieces without centering. Extreme high precision. Applicable for sheet steel, sheet brass, sheet aluminium, sheet zinc, sheet copper, plastic sheets.
HSSE Co 5:
Heavy-duty high speed steel with 5 % cobalt content.
High ductility and heat resistance, for drilling holes in difficult-to-machine materials with a strength of up to 1100 N/mm².
Centre point:
Applications: for drilling sheet-metal and soft materials, for blind holes with flat bottoms. Advantages: good centring, minimal formation of burrs when through-drilling, precise drilling in thin sheets and pipes, does not catch.
Available in diameters of 2.5 mm upwards. Disadvantages: sensitive to impact and one-way loading. Can only be ground to perfection by machine.
TiCN:
The titanium carbon nitride coating offers high strength and good ductility. It has a very low friction coefficient. Suitable for drilling high strength steel. Cooling is required.
