Wohlhaupter India Pvt. Ltd. expands its T-A Pro product line with new drill and chamfer holders, enabling single-operation holemaking, reducing cycle times, and enhancing efficiency across automotive, heavy equipment, and mould industries.

Wohlhaupter India Pvt. Ltd. provides expert engineering, technical support and onsite application services within India for Wohlhaupter GmbH and Allied Machine and Engineering Corp., leading manufacturers of holemaking and finishing tooling systems for the manufacturing industry. The company continues to expand the 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.

Ideal for industries such as automotive, heavy equipment, and mould 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 subseries A and C. Additionally, the T-A Pro drill and chamfer holders offer the following functions:

1. Provide a 0.040 inch (1.0 millimetre) x 45 degree (minimum) chamfer for various thread specifications, including: UN | ISO | NPT | NPS | BSPP | BSPT | BSW.

2. Chamfer/edge break the top of the hole to reduce secondary deburring

3. Pre-drill for extended length holders from 10xD to 15xD due to the flute length of the tool being at a minimum of 2xD.

Compared to competitor offerings, the T-A Pro drill and chamfer body provides a larger 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, customised solutions tailored specifically to the application are available.

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