Spot Drill 55 4.0xd4x50 90°

Description

Spot Drill 55 4.0xD4x50 90° is a precision solid carbide spot drilling tool developed for accurate hole positioning, centering, and light chamfering in CNC machining operations. Designed for materials up to 55 HRC, this spot drill ensures precise hole location, reduced drill walking, and extended life of subsequent twist drills, making it an essential tool for consistent and repeatable machining. With a 4 mm cutting diameter, D4 shank, 50 mm overall length, and a 90-degree point angle, it is ideal for compact setups and fine-detail work.

Manufactured from high-quality solid carbide, the Spot Drill 55 series offers excellent edge strength, wear resistance, and thermal stability. It performs reliably on P20 steel, EN8, EN19, mild steel, alloy steel, and stainless steel (SS304)—materials commonly used in die & mould, automotive, and general engineering applications. The optimized point geometry produces clean, accurate spotting with minimal burr formation, even at higher spindle speeds.

The rigid carbide body minimizes vibration and deflection, delivering better surface finish and positional accuracy. The 90° angle is widely preferred for standard drilling preparation and countersinking compatibility, ensuring smooth transitions to drilling operations. Efficient chip formation reduces heat concentration at the cutting edge, supporting longer tool life during continuous production.
