Allied Machine Drill, Chamfer Holders Reduce Tool Changes

Allied Machine and Engineering has expanded its T-A Pro product line with the release of drill and chamfer holders. This product extension gives users the ability to drill and chamfer a hole in a single operation, eliminating the need for secondary operations like chamfering and/or deburring as well as the need for a tool change.

Well suited for industries such as automotive, heavy equipment and mold and die where threaded holes are numerous and reducing cycle times is key, these holders are compatible with all existing T-A Pro inserts and are available in Y-3 series and sub series A and C.

Additionally, the T-A Pro drill and chamfer holders offer the following functions:

• Provide a 0.040" (1.0 mm) × 45-degree (minimum) chamfer for various thread specifications, including UN, ISO, NPT, NPS, BSPP, BSPT and BSW 
• Chamfer/edge break the top of the hole to reduce secondary deburring
• Pre-drill for extended length holders from 10 × D to 15 × D due to the flute length of the tool being at a minimum 2 × D

Compared to competitor offerings, the T-A Pro drill and chamfer body provides a large range of diameters that can be drilled and chamfered with a single tool — delivering more flexibility out of a single drill body without sacrificing performance. Targeted around thread sizes, this product offers an easy selection guide for users when choosing the correct drill body and insert combination for the job. However, if the length and diameter specifications do not meet the customer’s requirements, customized solutions tailored specifically to the application are available.

John Weniger, product manager of the T-A Pro line, shares, “We’ve taken the specialized performance our customers count on and transformed it into a standard solution — designed to simplify setups, cut cycle times and drive higher throughput.”
