Destec Engineering Ltd is saving time and money by using Walter Titex XD deep hole drills to produce a series of 5 mm to 20 mm diameter holes (autoclave ports) to depths of 250 mm in a range of materials including carbon steel and super alloys.
In one case – producing holes of 5 mm diameter by 240 mm deep - the solid carbide drills have reduced cycle times by seven hours and have also increased hole quality.
Introduced two years ago by the specialist manufacturer and supplier of high-pressure containment equipment, portable machine tools and on-site machining services to the worldwide oil and gas sector, the Titex drills have not only cut hole production times from 30 minutes per hole down to just five minutes, but they have also eliminated the problems formerly encountered with frequent tool breakage and tool wander, as well as insufficient swarf clearance.
The Titex XD range, available in the diameter range of 3 mm to 12 mm, feature four lands for optimum hole quality, especially in workpieces with inclined hole exits and cross holes, and boast a tip coating of TTP, specifically designed for deep hole applications, giving excellent hot hardness to counter generated cutting temperatures, high oxidation resistance and outstanding frictional properties.
