High-feed, robust-cut indexable drill covers carbon steel, cast iron and alloy steel, greatly simplifying pre-machining procedures for machine shops
[DEZHOU, CHINA – June 2, 2026] – Drillstar launches its upgraded heavy-duty indexable drill, engineered to solve long-standing machining troubles of unstable drilling on sloped and irregular workpiece surfaces, delivering outstanding versatility across mainstream ferrous metal processing.
Conventional solid drills usually require face milling or spot-drilling beforehand to avoid wandering and chipping when drilling angled or rough blank surfaces, raising extra production time and cost. Designed with optimized cutting geometry and rigid tool body, the new heavy-duty indexable drill can start drilling directly on uneven, curved or inclined workpieces without pre-flattening, effectively preventing drill skidding, offset and insert breakage during entry cut.
This robust indexable drill is specially formulated for routine hole machining on carbon steel, cast iron and alloy steel, three most widely-used materials in general machinery, automotive and mold manufacturing industries. Supporting aggressive feed rate and heavy cutting load, it remarkably boosts machining efficiency versus traditional twist drills. Equipped with indexable carbide inserts, users only replace worn cutting tips instead of the whole drill body, cutting down overall tool expenditure significantly.
“Many fabricators waste hours on pre-machining uneven casting and forging surfaces,” said the company’s product manager. “Our new heavy-duty indexable drill eliminates preparatory machining steps, helping clients shorten production cycles and lower comprehensive processing costs.”
Available in a full range of standard diameters, the drill fits CNC lathes, machining centers and conventional drilling equipment, ideal for batch production and flexible job-shop processing.
