CoroDrill® 860 is a solid carbide drill designed for a fast and problem-free drilling. It maximizes productivity through high metal cutting efficiency and machine utilization. With excellent chip evacuation in long and short chipping materials, CoroDrill 860 provides green light machining at high penetration rates. The CoroDrill 860 product offer consists of three drill geometries—optimized for steel, stainless steel, and aluminum. The drill comes in lengths 3-8×D as standard. Extended assortment is available as Tailor Made.

Application
860-PM: Long- and short-chipping steel materials, such as unalloyed steels, low carbon steels, low alloy steels, high alloy steels and steel castings
860-NM: Non-ferrous materials, such as aluminum alloys, magnesium and copper-based alloys, including bronze
860-MM: Long-chipping stainless steel materials such as austenitic, super austenitic, ferritic and duplex stainless steels
Standard diameter range:
–PM and –NM: 3-20 mm (0.118-0.787 inch)
–MM: 3-16 mm (0.118-0.629 inch) Drill lengths: 3-8 × drill diameter
Achievable hole tolerance:
–PM and –NM: H8-H9
–MM: H6-H8
