55 series- HRC55 Solid Carbide Spot Drill (90° Point)

Crafted from premium HRC55 solid carbide, the HN55 SDS spot drill delivers exceptional strength and wear resistance for accurate hole positioning. Available in 2- and 4-flute designs and traditional point angles (60°, 90°, 120°), this precision spot drill ensures accurate centering and prevents drill wander—ideal for tool & die, aerospace, and precision machining.

Typical Applications

• Pre-drilling spot for precision guided holes in hardened steels, tool steels, and tough alloys.

• Template-indexed spot drilling in CNC cells where positional accuracy is critical.

• Preventing drill wander on angled, curved, or heat-treated parts.

• Repetitive setup environments, such as fixtures in aerospace, medical, and die-making.
