Spot Drill 55 6x6x50 90°

Description

Spot Drill 55 6x6x50 90° is a precision solid carbide spot drilling tool designed for accurate hole positioning, centering, and light chamfering in CNC machining operations. Engineered for materials up to 55 HRC, this spot drill helps eliminate drill wander, improves hole accuracy, and extends the life of subsequent twist drills—making it an essential tool for consistent and repeatable machining. With a 6 mm cutting diameter, D6 shank, 50 mm overall length, and a 90-degree point angle, it is ideal for general-purpose spotting and countersinking tasks.

Manufactured from high-quality solid carbide, the Spot Drill 55 series delivers 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 manufacturing, automotive components, and general engineering. The optimized point geometry ensures clean, accurate spot formation with minimal burrs, even at higher spindle speeds.

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