Solid Carbide Micro Drill produces holes from 0.073-0.116 in. in diameter.
Press Release Summary:
Featuring thin TiAlN coating that helps retain cutting edge geometry, CoroDrill 862 produces holes in steel, stainless steel, cast iron, and aluminum. Post treatment, combined with specially designed point geometry, minimizes thrust forces, while Advanced Chip Management flute geometry helps evacuate chips. Available in drill lengths of 8-12 x D, CoroDrill 862 achieves hole tolerance of IT8-IT9. Internal coolant holes deliver coolant directly to tip of drill, even at deep drilling depths.
Original Press Release:
New Sandvik Coromant CoroDrill® 862 Provides Outstanding Micro-Drilling Performance
Highly productive micro-holes up to 12 x drill diameter
Fair Lawn, N.J. - The new Sandvik Coromant solid carbide micro drills offer outstanding performance for holes from 0.073 inches to 0.116 inches in diameter. The CoroDrill 862 has a thin TiAlN coating that helps retain cutting edge geometry and provides a smooth surface for chip evacuation. This helps prolong tool life in workpiece materials that include steel, stainless steel, cast iron and aluminum.
The innovative post treatment on the CoroDrill 862, combined with specially designed point geometry, reduces the thrust forces and promotes fast and efficient chip removal. This is aided further by Advanced Chip Management (ACM) flute geometry, which helps evacuate the chips. This is vital in micro-drilling as even the smallest accumulation can lead to problems such as drill breakage, loss of precision, downtime and scrap.
The CoroDrill 862 also provides good hole entry and exit, and achievable hole tolerance of IT8-IT9. Internal coolant holes deliver coolant directly to the tip of the drill, even at deep drilling depths, to further assist precision and chip removal.
Available in drill lengths of 8-12 x D, the drills are only for use with HydroGrip® high precision chucks from Sandvik Coromant.
