Bulldog Slots into Quickgrind Portfolio

One of the highlights in the new Quickgrind ‘Infinite Possibilities’ brochure is the new Bulldog range of end mills. Developed for the mould and die industry, the Bulldog is available in an almost infinite choice of size, diameter, radius and reach.

Described as a state-of-the-art masterpiece of engineering excellence, the Bulldog produces exceptional results with significant productivity increases and reduced production costs. The Bulldog has been designed to reduce vibration under heavy cutting conditions that generate extremely high volume metal removal rates. Perfect for deep pocketing and slotting difficult to machine materials, the Bulldog prevents tool ‘push-off’ which is commonplace with inferior quality tools.

What makes the Bulldog ideal for the mould and die sector is its suitability for roughing mould and die steels and tool steels such as H11, H13, D2 and P20 as well as hardened alloys up to 62HRc. The exceptional performance on these materials is credit to a range of features that include force resistive micrograin carbide composition with a superior coating and an unequal helix and variable flute design. This is supported by enhanced radius geometry and strengthened core, which is optimised for heavy material removal rates.

The Bulldog is also available with a plain or Weldon shank whilst the overall length, flute length, neck length, diameter and corner radii can be specified to the exact specifications of the customer. For the end user all these features provide the capacity to increase productivity and metal removal rates through high speed and feed cutting. Additionally, the Quickgrind Xred and MX coatings aid chip flow and demonstrate excellent wear resistance.

The unequal helix suppresses vibration and the harmonic effect which reduces machining forces to increase tool life and generate a smooth cutting action. This geometry design also ensures a high level of stability during machining. When using a tool of such a high performance level, Quickgrind recommends that users always apply toolholders with a high level of concentricity whilst the workholding configuration must demonstrate high clamping forces to maximise performance.
