Company > About Wohlhaupter®

The company's history is a story with a future, characterized by innovations. In 1929, Emil Wohlhaupter founded the company as a small mechanical workshop, which initially started as a repair shop for cutting and stamping tools and devices. Today, Wohlhaupter is known all over the world as a manufacturer of modular tool systems for machining centers and millturns, facing and boring heads, grooving heads, clamping tools and customized solutions for boring operations.
Allied World Wide
Founded by Emil Wohlhaupter in 1929, Wohlhaupter has grown into a leading manufacturer of precision boring systems. The second generation of Wohlhaupter continued to expand their product line significantly from the 1960’s into the next century. For almost 20 years now, Frank-M. Wohlhaupter, a third generation Wohlhaupter family member, continues to lead the innovative manufacturer of precision tools. Initially the technical director of Wohlhaupter GmbH, Frank Wohlhaupter currently orchestrates operations as a managing partner. In 2016, Wohlhaupter expanded its product offering and expert boring application services even further when the majority shares were acquired by Allied Machine and Engineering. Wohlhaupter and Allied Machine have partnered to strengthen their position as the only manufacturers to focus solely on holemaking and hole finishing applications for the metal-cutting industry.

Our Milestones

Founding year in Stuttgart-Feuerbach

On October 1, 1929, Emil Wohlhaupter founds a small mechanical workshop in Stuttgart-Feuerbach. In a rented room measuring 40 square meters, cutting and stamping tools and devices are reconditioned - purely by hand. Some years later, the company is subcontracted to carry out small-scale batch production. The clients are very satisfied with the work. The client base grows. The number of employees increases to fifteen. The current space is no longer sufficient, so in 1936 a small factory is rented in Stuttgart-Feuerbach.

Introduction of the Universal Facing and Boring Head UPA

After months of strenuous activity, the first model is developed in 1936, and a year later embraced wholeheartedly by the world of industry at the Leipzig Trade Fair. Universal Facing and Boring Heads are used on universal milling and boring machines, boring mills, jig boring machines and milling machines of all kinds, for machining stationary workpieces in individual and batch production. Around the world, the UPA becomes synonymous with the company's name.

Move from Feuerbach to Frickenhausen

In February 1944, the building and machines suffer considerable damage following an air raid. Through family ties, the company is able to move its headquarters to Frickenhausen.

"MultiBore", the world's first Modular Tool System

With the versatile and extensive MultiBore tool range, complete tools can be put together quickly and precisely. The master shanks that connect the modular MultiBore components to the machine tool are supplied for all kinds of machine tool. The MultiBore boring tools fit directly in the master shanks, or can be made into workpiece-adapted complete tools with the aid of intermediate modules.

Move to the new business premises in Frickenhausen

The move to new manufacturing and office premises provides space for more than 220 employees, space for modern production systems, space to satisfy customers' demanding requirements in the future, too.

Automatic Facing and Boring Head APD for machining centers and special-purpose machines. One tool - numerous machining possibilities

The Wohlhaupter APD 120-36 Facing and Boring Head is developed for use on machining centers, and is designed for a self-contained work process

Production launch of the Hollow Taper Shank HSK

Even prior to standardization in 1996, Wohlhaupter and its partners jointly develop the Hollow Taper Shank HSK, which excels through its very high radial rigidity, its torque transmission, its precise tool changing accuracy and its defined radial positioning.

The first self-balancing Precision Boring Tool from the "Balance" series

Right on time for the EMO Trade Fair in Hanover, Wohlhaupter presents the world's first Balance Precision Boring Tool with auto-balance for finish machining. This is specially developed to minimize the residual imbalance produced by adjustments to the insert holder diameter.

The First "Alu-Line" Aluminum Precision Boring Tools - Welcome to the 3rd Generation

Wohlhaupter sets standards in weight reduction with the launch of Alu-Line lightweight tools. Finally, large tools can be easily integrated into the production process - with simple handling and maximum precision. At the same time, the 3rd generation of the Wohlhaupter family takes charge of the company.

Grooving Head EK - the trailblazing innovation for grooving operations in large-scale production

Pure innovation for internal and external grooving in batch production: the trailblazing grooving head from Wohlhaupter combines linear single-cutting feed with multi-cutting circular milling. Its most important features are: improved surface quality, machining times reduced by up to 80%, and process reliability thanks to electronic tool monitoring.

"Combi-Line" - Rough and Finish Machining in a Single Operation

Combi-Line is synonymous with the combined rough and finish machining of bores in a single operation. The advantages of this series are shorter process times, simple handling and a compact design. Combi-Line is a tool for both small and large-scale production.

Modular Insert Drills with four effective cutting edges

With this completely new and pioneering insert drill series, Wohlhaupter offers a state-of-the-art modular solution that can only achieve its best performance with the plane-parallel contact of the MVS connection. Insert drills are modular in design and therefore ideal for the internationally proven MultiBore range with its unmatched diversity.

Foundation of the US subsidiary "Wohlhaupter Corp." in Dayton, Ohio

After careful consideration of how best to work the American market, in summer 2002 the foundations are laid for the establishment of our own sales subsidiary. Together with Karl Hochuli from Chillicothe, Ohio, the course towards future cooperation is set at an early stage. We quickly find a suitable partner in the shape of a regional dealer, the Mackintosh Tool Company, on whose premises the Wohlhaupter Corp. is to be situated. Now, since December 2002, the Wohlhaupter Corp., based in Centerville/Dayton, Ohio, has been operating in the U.S. and works the U.S. market from within the country. Karl Hochuli heads the sales subsidiary as president of the corporation. An ever growing network of dealers and sharply increasing numbers of customers from all industries endorse our decision, after 9/11, to take the helm in the U.S. ourselves. A group of our own experienced application engineers make up the team and look after customers within the country.

"DigiBore", the Precision Boring Tool with integrated opto-electronic traverse measurement and digital display

Wohlhaupter continues its success story with the highly precise DigiBore Precision Boring Tool. This tool sets new standards for reliability and handling. For fast and reliable adjustment in batch and individual production, DigiBore is the right choice.

Wohlhaupter Exhibits at the IMTS in Chicago, IL, USA

Like many other major trade fairs, the IMTS International Manufacturing Technology Show is held every other year. An impressive presentation increases awareness of the company on the huge American market as a manufacturer of precision tools and a partner for all manner of complex boring operations.

Balance series is further developed

Back in 1993, Wohlhaupter launched the Balance series onto the market as the first tool for finish machining with auto-balance. The logical further development of these tools guarantees maximum bore quality at high cutting speeds with state-of-the-art technology, even from Ø 20 mm. The tools, with a boring diameter of 65 mm or more, feature a lightweight aluminum construction. Wohlhaupter is a pioneer in this technology as well, and helps to minimize customers' production costs.

Wohlhaupter takes over combination-cut boring from the Koyemann company

Koyemann combination-cut boring is a double-edged cutting process for the rough and finish machining of bores in just a single operation. This year, Wohlhaupter purchases the rights to the Koyemann brand.

Alu-Line is further developed from 500 mm to 3,255 mm in diameter

For 10 years now, Wohlhaupter has repeatedly introduced new features to its Alu-Line series for the internal machining of large bores. Using its huge store of product and system knowledge, Wohlhaupter redesigns the standard range to cover a range from Ø 500 - 3,255 mm, and integrates it seamlessly in the existing Alu-Line range from Ø 200 - 500 mm.
