To enhance hole-making performance for end users, Mapal has introduced its Drill-Ream product line. The underlying philosophy of Drill-Ream is to combine individual work steps to improve precision and consistency, reduce set-ups, and cut machining times. For machining bores on a range of materials that vary from cast iron through to aluminium, Drill-Ream incorporates a pyramid tip. The tool combines pilot drilling, drilling and subsequent bore reaming in a single pass.
Solid-carbide Drill-Ream tools are available with through-coolant to evacuate chips, prolong tool life and increase cutting speeds and feeds. Offered in incremental diameters from 5.97 to 12.72 mm, the Drill-Ream has been developed with optimised self-centring geometry that guarantees drill position and precision.
Also at MACH will be the Mega-Deep-Drill and Mega-Pilot-Drill, which have been introduced for drilling deep bores with small diameters. The Mega-Deep-Drill deep hole drill has been developed for hole diameters from 1 to 2.9 mm. Thanks to a newly designed chip flute and special face geometry, high feeds and cutting speeds are possible, says Mapal. Furthermore, the Mega-Deep-Drill has a coated head that ensures optimal chip removal.
To bolster its drilling offer, Mapal will introduce the Mega-Drill-Hardened and the Mega-Speed-Drill-Inox at MACH, for drilling to depths of 8xD and 12xD. For the Mega-Drill-Hardened, the micro-grain carbide substrate and tool geometry have been developed to machine hard materials up to 65 HRc. On the Mega-Speed-Drill-Inox, a newly devised groove profile has been developed for reaching drilling depths up to 12xD.
For engineers drilling steel with unstable machining conditions, a further introduction from Mapal will be the QTD pyramid-tipped drill. The QTD series uses the smallest possible amount of carbide with an indexable insert that centres itself.
Also on the stand will be examples from Mapal’s redesigned chuck range. One of the elements in the latest concept is the brilliant surface finish, which ensures the chucks are more resistant to corrosion than previous versions. A further design requirement was ‘foolproof-handling’, creating something that delivers the easy and self-explanatory handling of chucks. These requirements have been addressed with blue-coloured features such as the actuating screws on hydraulic chucks. The product and design engineers also optimised the chucks by undertaking a complete review of the weight, material selection and size.
