Designed for exceptional precision and extended tool life, this combination tool features a hardened TiN coated High Speed Steel body, a 60° countersink included angle, and a sharp 118° drill point. Ideal for metalworking, sheet fabrication, aerospace, and any application where clean, burr‑free countersinks and accurate pilot holes are required.
Material: High Speed Steel (HSS), with Titanium Nitride (TiN) coating for reduced wear and increased lubrication.
Countersink angle: 60° included angle for clean chamfers.

Drill point: 118° angle to help reduce walking and ensure good centering.
Trade size: #5; Body diameter: 7/16"; Drill point diameter: 3/16"; Overall length: 70mm
Finish: TiN Coated; End Type: Double; Cutting Direction: Right Hand; Cutting Edge Style: Plain.
The TiN coating reduces friction and heat build‑up to prolong tool life, especially in tougher materials.
Combined drill & countersink action saves time and ensures alignment between the hole and the chamfer.
#5 size delivers a balance between strength and precision—good for small pilot holes with firm stability.
Right‑hand cut and plain edge allow clean chip formation and easy regrinding when needed.
70mm overall length gives enough reach for many light to medium duty jobs without sacrificing rigidity.
