Each drill bit for metal hole alloy processing costs

Each hole machining productivity or cost is the most important factor in drilling impact. To improve productivity, the carbide drill bits manufacturers are working on a variety of operations can be integrated step processing method, and developing high feed, high speed processing of the drilling tool. The newly developed replaceable carbide drill crown has excellent machining economy. Carbide crown replacement easy and high repeatability, processing workshops available drill body with a plurality of teeth crowns, to the processing of different pore sizes of holes. This modular drilling system can reduce 12 ~ 20mm diameter drill bit manufacturing costs and administrative expenses, while also saving the cost of backup tool when welding or solid carbide drills were reground needed. When considering the cost of processing each hole, should also be taken into account the total life of the core drill bit. In general, a solid carbide drill regrinding only 7 to 10 times, a welded carbide drill regrinding only 3 to 4 times, and replaceable carbide drill crown in the processing of steel material , its steel hammer drill bits body can be replaced at least 20 to 30 times the tooth crown.

Features and choice of solid carbide drills

Solid carbide drill bits is a complete carbide rods, use grinder processing. High strength, high hardness properties, fast cutting speed, wear resistance, red hardness and good, suitable for processing a variety of materials components. By cooling structure can be divided into non-cooling holes and there are two types of cooling holes. 1. Characteristics and uses (1) rigid, high strength, easy access to high precision core drill bit. (2) the material can be suitable for more complex drilling, selects a higher cutting speed. (3) effective to reduce chipping, has good wear resistance. (4) multi-layer geometry cutting tip edge, improving chip performance, maintain a smaller cutting resistance. (5) In addition to commonly used rectangular handle, the wide range of handles, suitable for a variety of drills, drilling machines equipped with. (6) compared with indexable insert drills, solid carbide hammer drill bits grinding times can be 7-10 times.

GUSHI drill bit for metal installation and removal

For a variety of installation and removal of the GUSHI drill bit for metal rig. Easy and reliable installation and removal.
  ⒈ GUSHI drill bits for metal installation

Slowly lifting GUSHI drill bit for metal cassette, the cassette will GUSHI drill bit for metal four legs into the four holes corresponding turntable rig, according to the choice of the appropriate size GUSHI drill bit for metal core GUSHI drill bit for metal box, lifting the GUSHI drill bit for metal into the GUSHI drill bit for metal core box inside the box and then will be notch and GUSHI hammer drill bits core GUSHI drill bit for metal dimples box corresponding installation will GUSHI drill bit for metal into the box GUSHI drill bit for metal, GUSHI drill bit for metal core that card on the turntable. Followed by spin coupling nut on the GUSHI drill bit for metal bit.
  ⒉ GUSHI drill bit for metal demolition

Lifting GUSHI drill bit for metal (with GUSHI drill bit for metal), the GUSHI drill bit for metal bit cassette as ① requires connection with the turntable, lifting the GUSHI drill bit for metal bit slow groove corresponding convex tip GUSHI drill bit for metal core box, and the GUSHI drill bit for metal bit stuck in the box, in order to recede GUSHI diamond glass drill bit , GUSHI drill bit for metal.
