Marathon-design

Drilling

Multiple performance compared to standard drills, Z2/V2. The round spur profile with shear cut, suitable for boring tear-free holes at high feed speeds. Ideal for machining panel materials coated with difficult surface coatings (e.g. thin decorative paper). High wear-resistant HW-quality, suitable for hardwood and wooden materials. Excellent chip clearance when deep boring from friction reducing tool body coatings. A loose countersink can be clamped on the shank WB 701-0-02.
