Step drills for metal

Drill stepped in metal, steel plate, acrylic glass and not. metal up to 4mm Range: 4-12mm (step 1mm) Material HSS - High Speed ??Steel Shank diameter: 6mm 8mm clamp with three flats for better fit. Stepped spiral drills

Diameter: 4-5-6-7-8-9-10-11-12mm Material: HSS Coating: TiAlN < br> Suitable for drilling into structural steel, CrNi steel and non-ferrous metals up to 5mm. PROGRIP system prevents slipping of the stem in the chuck and optimally transmits torque Spiral groove guarantees quiet operation and high drilling performance Edges in a single step The coating increases the service life of the drill bit but must not overheat! Procedure: High speed for drilling small diameters, when drilling larger diameters, the need for speed is gradually reduced due to increasing circumferential speed. When the coating overheats, the blade is knocked and the blade has to be sanded.

Diameter: Clamping diameter: 10mm Material: HSS Coating: TiAlN Suitable for drilling into building steel, CrNi steel and non-ferrous metals up to 5mm. PROGRIP system prevents slipping of the stem in the chuck and optimally transmits torque Spiral groove guarantees quiet operation and high drilling performance Edges in a single step The coating increases the service life of the drill bit but must not overheat! Procedure: High speed for drilling small diameters, when drilling larger diameters, the need for speed is gradually reduced due to increasing circumferential speed.
