Application:
- Suggested Parameters for HW dowel drills bits are as below:
- Used for CNC and drill rig machining
- Speed:4500-8000(r/min)
- Feeding speed:2-8(m/min)
Maximum drilling depth for length 57mm drills is 20mm, for 70mm drills, Max drilling depth is 33mm.
The above dowel drills can be used for boring machines blind drilling of solid wood, MDF wood-based Panel, wood composites, plastic and laminated materials..Cemented carbide is a hard material, widely used in wood processing and metal processing. It consists of cemented carbide fine particles, which are bonded by a binder metal to form a composite material. References to “carbide” or “tungsten carbide” in an industrial environment generally refer to these cemented carbide materials.Most of the time, cemented carbide dowel drill bits will provide a better surface finish on the parts and can be processed faster than HSS and other steel tools.
