Drills Tackle Tough Materials, Flat Holes
IMTS 2018: OSG USA’s A-Drill series of carbide drills covers a range of applications and materials.
OSG USA’s A-Drill series includes the Exocard AD, ADO, ADO-SUS and ADF drills.
Suitable for both ferrous and non-ferrous materials, the Exocarb AD and ADO carbide drills are designed to provide high point strength with low cutting force. EgiAs coating, which features high wear and heat resistance characteristics, contributes to extended tool life. A coolant-through option is available.
The Exocarb ADO-SUS coolant-fed carbide drill features a coolant hole shape and tool geometry designed specifically for drilling difficult-to-machine materials like stainless steel and titanium.
The Exocarb ADF carbide flat drill is designed to machine flat holes without a separate end mill. One-step drilling reduces machining time and eases tool management. It is designed for work on inclined surfaces and curved surfaces and can perform counterboring, eccentric-hole and thin-plate operations.
Thread milling and tapping are two methods for machining threads in a hole. Tapping is more popular, but thread milling has several advantages that might be important in your application.
Recent tap geometry refinement and advances in coating technologies have made the chip-less, cold-forming operation suitable for a wider range of workpiece materials.
One of the most common methods of tapping in use today on CNC machines is 'rigid tapping' or 'synchronous feed tapping.' A rigid tapping cycle synchronizes the machine spindle rotation and feed to match a specific thread pitch. Since the feed into the hole is synchronized, in theory a solid holder without any tension-compression can be used.
