These T-A spade drill inserts are an excellent choice for general purpose drilling. The design provides fast penetration rates that produce good hole size and finish. The drills' standard geometry combines highly efficient and stable cutting action to minimize power consumption. Each drill is recommended for use with most steels including 4150, cast irons, high-temperature alloys, and aluminium alloys.

Features and Benefits
• Insert design offers substantial increases in penetration rates and tool life and improves centering, drill stability, and chip formation
• Provides smoother breakout on through hole applications
• Super cobalt construction is suitable for machining a wide range of materials
