Deburring specialist since 1961

First, a disbelievingly admired idea was followed by worldwide recognition. Today, HEULE is synonymous with solving deburring problems. 


Heinrich Heule established his company in 1961 as a contract manufacturing company. Already with one of his first commissions he reached his limits: It was to chamfer the insides of a fork piece in full-scale series production quickly and economically. At the time, there was no suitable tool for that purpose. He therefore created one himself, thereby filling a gap in the market. The cornerstone for a flourishing enterprise was laid. 


Over the last 60 years, HEULE Precision Tools has been setting the benchmark in the development and manufacture of tools for front and back machining of bores in a single pass. Ulf Heule now manages the company, and the third generation is already working for HEULE. Everything is in place for the next 60 years of company history.
