SARA-DRILL cutting edge ASP30 49mm for boring head A1-55

• Machining of bore holes from O 49 to 270 mm
• For machines with low drive power
• Low-vibration, equipment-friendly machining with up to 50% less drive power
• Drilling in a single operation without centering and pre-drilling
• No front face planning required
• Cost-efficient boring system, since differences in diameter of up to 30 mm can be machined with one boring head by changing the cutting edges
• Variable drilling depths of up to 15 x D due to holding fixture system with pluggable extensions
• Internal coolant supply directly to the cutting edge, no high-pressure pump required
• For rotating tools, the coolant is supplied via a coolant ring
• Short chips due to chip-separating grooves in the roughing blade, no chip removal, even with extremely deep bores
• Also for use on vertically operating machines
• Low tool costs as wear is limited to the cutting edges and center bit
• Unproblematic regrinding of the center bit and the cutting edges (in pairs) using the grinding fixture or the tool grinding machine
• Cutting material:
  Cutting edge HSS-E-PM ASP30, ASP30 TiN
  HSS center bit
• For use on all machine tools as a rotating or stationary tool especially for machining large bore diameters on machines with low drive power
• Caution: Not suitable for boring out existing holes!

• For SARADRILL solid drilling tools
• The cutting edges are delivered in pairs, ie 1 roughing blade and 1 finishing blade.
• Note for machining blind holes:
  The finishing blade can be adjusted from 3 to 10 mm, depending on the size of the drill head, to machine intermediate dimensions. (Not permissible for machining through-holes!)
• Caution: The cutting edges may only be replaced in pairs to prevent the risk of breakage!
• Prices per pair (1 roughing blade and 1 finishing blade)
