- 5-piece set consisting of:
- WS Bormax® (1622) Ø 22, 25, 38, 42 mm
- Extension (1639) GL 250 mm
- CrushGrind grinder GL 195 mm included
- in wooden box made of beech wood
Quality level: professional
Version: WS-Bormax® 2.0! Center point with cutting geometry. Two offset grooved main cutting edges (from Ø 11 mm) and the toothed circumferential cutting edge with longitudinal grooves mean that significantly less feed force is required and minimize friction and the heat generated as a result. Hexagonal shank for better power transmission.
Tool material: alloyed tool steel.
Recommended speed: 900 - 3200 rpm. e.g. Ø 35 mm 1500 min-1 in laminated beams.
Application: Rapid drilling in softwood, European hardwood, chipboard, MDF boards, etc. Very fast chipping of solid wood and chipboard with significantly lower feed forces and significantly faster drilling than with conventional Forstner bits.
Tip: Great for hands-free operation and stationary use. Due to the very low heat development, an incredibly long service life with the highest drilling quality. In connection with the extensions 1639 ideally suited for deep hole drilling.
