Drill for machining ultra-deep minute holes Epoch Micro Step Borer S

Enables ultra-deep drilling of minute holes Features of EMSBS New chip-removal stopper technology + high-rigidity neck shape enables high-accuracy drilling of minute holes. Thinning flute shape achieves even higher machining accuracy (Thinning: Drill diameter > φ0.1) Combined with a special starter, it enables stable deep drilling of minute holes. Two types of coating to match various applications For product sizes other than standard product sizes, refer to made-to-order products (up to 100D possible). SD Non ferrous Carbon metal steel Stainless steel Pre-hardened steel New chip-removal stopper...

Epoch Micro Step Borer S Item Code • This standard cutting condition table is intended as reference cutting conditions. The conditions should be adjusted as necessary according to the actual conditions of machined shape, purpose, machine used, etc. • In general, water-soluble or oil-based coolant should be used to ensure chip removal. • Always use with a G83 program (Peck drilling cycle). • Under-neck length (R2) conforms to through-hole drilling depth. • When drilling through holes, drill the through hole to a depth of between 20% and 30% of the diameter from the tip of the tool. Ex.: For work...

Epoch Micro Starter O Recommended cutting conditions Epoch Micro Starter Item Code • These Recommended Cutting Conditions indicate only the rule of a thumb for the cutting conditions. In actual machining, the condition should be adjusted according to the machining shape, purpose and the machine type. • In general, water-soluble or oil-based coolant should be used to ensure chip removal. • Always use with a G83 program (Peck drilling cycle). • Hole depth: Be sure to drill to a depth of 60% of
