Allied Machine to Launch New Drilling System Fall 2020 – T-A Pro

Allied Machine releases the T-A Pro replaceable insert drill this October. This fresh take on their tried-and-true spade drill achieves penetration rates once thought unachievable by a replaceable tip drilling system.

Dover, OH - Allied Machine and Engineering proudly announces their revolutionary high-penetration drilling system, the T-A Pro. After 35 years of spade drilling success with their iconic T-A (Throw Away) insert, the best just got better. Allied Machine's team of engineers developed technology that takes THE "go-to" solution for general purpose holemaking to a performance level previously unachievable by a spade insert.


The T-A Pro drill combines material-specific insert geometries, a redesigned drill body, and a proprietary coolant-through system to allow penetration rates which run at speeds nearly 30% faster than other high-performance drills on the market. Coolant outlets are designed to direct maximum flow to the cutting edge providing quick heat extraction where it is most critical - even at significantly higher speeds. Material-specific insert geometries produce impeccable chip formation and the drill body incorporates straight flutes redesigned for maximum coolant flow and excellent rigidity. These design elements combine to extend tool life, create consistent quality holes, and provide superior chip evacuation. As a result, the T-A Pro drill offers machine shops and high production manufacturers a spade drill with incredible speed and a cost per hole averaging 25% less than existing drills.

The T-A Pro drilling system will be available in diameters ranging from 0.4370" - 1.882" (11.1mm - 47.80mm) and is ideal for holes ranging in 1xD, 3xD, 5xD, 7xD, 10xD, 12xD, and 15xD depths. The drill will be stocked in both imperial and metric shanks, with flat and cylindrical variants. The carbide insert geometries offered initially will cater to the following ISO material classes:

• Steel (P) with AM300 coating
• Cast iron (K), with TiAlN coating
• Non-ferrous (N) with TiCN coating

Product manager, Sal Deluca, states, "The T-A Pro drill is designed for use in applications ranging well beyond general purpose drilling. It truly will target all industries, offering phenomenal tool life at high penetration rates, especially in situations where the balance of chip formation at high penetration is critical."

The T-A Pro drilling system will be available to order from Allied Machine's distributor partners in late October. For more information or to request a free demonstration please visit www.alliedmachine.com/contact or call 1 (330) 343-4283 to be connected with field support in your area.

T.J. Davies' Retention Knobs

T.J. Davies' Retention Knobs

Our retention knobs are manufactured above international standards or to machine builder specifications. Retention knobs are manufactured utilizing AMS-6274/AISI-8620 alloy steel drawn in the United States. Threads are single-pointed on our lathes while manufacturing all other retention knob features to ensure high concentricity. Our process ensures that our threads are balanced (lead in/lead out at 180 degrees.) Each retention knob is carburized (hardened) to 58-62HRC, and case depth is .020-.030. Core hardness 40HRC. Each retention knob is coated utilizing a hot black oxide coating to military specifications. Our retention knobs are 100% covered in black oxide to prevent rust. All retention knob surfaces (not just mating surfaces) have a precision finish of 32 RMA micro or better: ISO grade 6N. Each retention knob is magnetic particle tested and tested at 2.5 times the pulling force of the drawbar. Certifications are maintained for each step in the manufacturing process for traceability.
