Allied Machine and Engineering is highlighting the T-A Pro high-penetration drilling system. With a diameter range of 0.3739"-1.8820" (9.50-47.80 mm), the T-A Pro is said to offer the consistency of a spade drill with the penetration rates of a high-performance drill.
The T-A Pro cutting tool solution is well suited for manufacturers to achieve extended tool life with high penetration rates, especially in situations where the balance of chip formation at high penetration rates is critical. The drill’s high-speed steel geometry insert not only provides good chip formation but also withstands interruptions. Pairing the drill with special guided T-A toolholders can aid in maintaining hole straightness throughout the cut. The carbide guides on the toolholder are an extension of the margins on the insert, providing straightness and stability.
Creating a 90-degree bend at the cross holes is often resolved by grinding custom forms into high-speed steel twist drills. However, with Allied Machine’s replaceable ball nose T-A insert, manufacturers have a secondary forming option for the bottom of holes to create a 90-degree bend at the intersection point. The company says these solutions enable a tool typically used for general-purpose machining to now be a go-to tool for holemaking applications.
