Allied Machine and Engineering, a manufacturer of holemaking and finishing cutting tools, highlights the T-A Pro high penetration drilling system for mold builders to utilize.

With tool life being one of the top challenges that moldmakers face when drilling, the T-A Pro achieves long tool life at high penetration rates — especially in situations where the balance of ideal chip formation at high penetration is critical. A high-speed steel substrate (X geometry) insert not only provides good chip formation, but also withstands the interruptions that are common within the cross holes of molds. Additionally, special guided T-A holders can assist with added hole straightness throughout the cut; the carbide guides on the holder are an extension of the margins on the insert, providing straightness and stability.

A final challenge often encountered in the mold and die industry is creating a 90-degree bend at the cross holes. While a common solution is grinding custom forms into high-speed steel twist drills, Allied Machine offers a replaceable ball nose T-A insert that is a secondary forming option for the bottom of holes to create that 90-degree bend at the intersection point.
