Allmatic: Workholding with efficiency & simplicity

Allmatic Vices are the top-notch solution for Workholding requirements, for:

  •  ·         3 - 5 Axis machining

  •  ·         Prismatic components

  •  ·         Non prismatic components – castings,  forgings

What makes Allmatic solutions different to the rest on the market is that they often fulfil the complete needs of a customers’ application, where they have previously had to spend time using multiple vices or resetting vices between applications.

 Allmatic’s intelligent engineering allows users to

  •  ·        Pre- select working pressures

  • ·         Minimum material work holding

  • ·         Gripp rough materials

 The Allmatic Gripp solutions, are a market leader when it comes to all types of component selection, with large capacity, high clamping force up to 7 tons and minimum deflections, for easy setting.

 Allmatic have been our work holding partner since 1972,  because of their pedigree when it comes to accurate pre- selection of material clamping pressures. Their vice performance, across the range, is second to none.

 A question clients always ask when enquiring about Allmatic Workholding is the cost, versus other brands, to which we always showcase the cost savings to be made,  long term. We know that budgets are always under pressure, but we also know that investing in Workholding pays dividends,  long term.

Single or in set-ups, Allmatic workholding solutions for all.

Stocdon Limited & Hermann Bilz - 35 years of engineering innovation.


Hermann Bilz have been supplying the world’s leading Automotive, Oil & Gas and businesses leading the way in engineering developments for over 80 years.

Stocdon are proud to hold the exclusive contract to supply the Hermann Bilz range to the UK & Irish market for 35 years. Over the years we have worked with Bilz’s engineers to create bespoke internal machining tool solutions for our customers.

If you have a complex challenge & a tight deadline, Stocdon & Hermann Bilz could provide you with a complete solution within just 6 weeks.

Stocdon & Hermann Bilz Case Studies

Case Study 1 - Drilling:

The customer required a tool to drill through the centre of a Connecting Rod with just a 66mm Diameter. Bilz created a 300mm Powerbore for this application, especially designed to cut through high grade steel 42CrMo4.

The Bilz Powerbore KSB Cartridge head uses indexable inserts and in this application could achieve up to 410 rev/min.

Case Study 2 - Countersinking:

The customer required a special solution to machine a Cylinder Head in GK-AlSi9Cu3. The Stocdon & Bilz solution was to create a Countersink tool that allowed the Cylinder Head to be cut via a Bore, Radius, Chamfer and Spotface tool in one application, saving the customer huge amounts of time rather than setting up four separate applications.

These tools can be created in special materials and a huge variety of lengths depending on the requirement.

Case Study 3 - Drilling:

A special dual purpose drill was required to work on a Truck Crankcase, to complete the transfer line process. A combi-drill was designed by Bilz & Stocdon to execute Drilling and Spotfacing applications together, allowing the customer to machine the Truck Crankcase with high accuracy (as the combined processes mean that there’s no need for aligning the tools twice as separate processes).

Case Study 4 - Back Spotfacing:

Bilz’s specialist tools for hard to reach areas are used most often in automotive engineering, in this instance for a Crankcase in grade GGG-50 SG Iron.

The solution for this customer was to supply an Autofacer tool, which allows for automatic forward and backward Spotfacing up to 2.2 x D.

Case Study 5 - Re-Boring:

The customer needed to Re-Bore a Disk Brake Caliper as part of the finishing machining process, in grade GGG-50 SG Iron.

The Bilz Preci-Cut system was used with a bespoke geometry to allow the customer to achieve 850 rev/min with a H7 tolerance.

Stocdon & Hermann Bilz can advise on all of these and a much wider range of specialist tools to suit your bespoke requirements. From Countersinking to Drilling to Chamfering, and specialise in high tech Back Spotfacing and Counterboring solutions for those difficult to reach applications.

We have provided solutions for Hydraulics, Turbine Housing, Valve Gear Covers, Steering Boxes and many more.
