Triple benefits

At the start of 2016 Mapal brought a number of innovations to the cutting tool industry with its patented QTD drill and HTC toolholders that are both produced with additive manufacturing technology. Now the company is strengthening its drilling line with the introduction of the new TTD-Tritan drill.

Mapal claims the TTD-Tritan is the industry's first triple cutting edged replaceable head drilling system. Interchangeable heads are the tools of choice for manufacturers aiming to streamline stock and reduce inventory, improve resource efficiency and combat raw material prices. With such incentives to develop interchangeable tooling systems, Mapal has created the new triple edged drill for replaceable head drilling applications.

The drill, tool head and toolholder are fixed by an innovative new interlocking Hirth serration system. This connection is extremely stable, so all the benefits and performance of the solid carbide equivalent can be achieved with the replaceable head variant.

The new line can be used reliably and with impressive stability even in difficult drilling applications such as inclined bore or cross bore drilling. The tool is perfectly centred via its pronounced drill tip and this ensures effective connection stability and rigidity. Performing on a level equal to solid carbide drills, the TTD-Tritan is said to incur lower customer costs by limiting the need for costly carbide. Furthermore, the drill reduces changeover times by enabling on-machine tip changes that also retain consistent precision performance.

The three cutting edges ensure a homogeneous load on the connection so the forces applied during machining are transmitted uniformly through the steel toolholder. In addition, the connection guarantees optimum torque transmission and radial run-out accuracy.

Initially developed as a 'universal variant', the TTD-Tritan is suitable for machining cast iron, stainless steel and carbon steels. The cutting edge geometry on the replaceable heads will improve drilling performance whilst reducing machining costs and tool inventory. Available in diameters from 12 to 32mm in 0.5mm increments, Mapal also has extended diameters for drilling up to 45mm.
