China Multi Tool Universal Blades Exporter & Exporters

A universal blade incorporates an engineered multi-pattern open-back or segmented arbor designed with 12 to 24 contact points. This stamping layout securely accommodates standard hex, round, star, and slotted pin configurations used by Milwaukee, DeWalt, Makita, Bosch (OIS models), Porter-Cable, and Rockwell. For specialized 3D interface requirements (such as Starlock systems), custom dedicated press dies are deployed to ensure rigid torque transfer without mechanical slip.

Quality assurance begins with raw material composition. Export-focused Chinese factories utilize laser-welded composite strips combining high-tensile alloy backing steel with M42 high-speed steel containing 8% cobalt. The teeth are CNC-milled rather than cold-pressed to maintain absolute geometric consistency and cutting angles. In addition, atmospheric controlled vacuum heat treatment prevents surface decarburization, producing a tooth tip hardness rating of HRC 66-68 while preserving core flexibility.

Yes. Complete OEM/ODM manufacturing capability is standard. Exporters supply full private-label services, including laser annealing and chemical etching of corporate logos, metric/imperial depth gauges, and batch numbers. Tooth coatings can be specified in black electrophoresis, PTFE non-stick coating, or Titanium Nitride (TiN) gold plating. Packaging solutions encompass bulk industrial cartons, anti-theft sliding blister packs, plastic storage tubs, and custom printed counter displays.

High Carbon Steel (HCS) blades are optimized for soft materials, timber, plywood, plastic, and drywall where high tooth flexibility minimizes breakage risks. Bi-Metal blades integrate cobalt teeth to withstand impact from occasional framing nails, copper piping, and structural fasteners. Carbide oscillating blades feature ultra-hard tungsten carbide teeth that cut through hardened structural screws (Grade 8), stainless steel bolts, fiber cement, and dense brickwork that instantly dull ordinary bi-metal blades.

Standard OEM production minimum order quantities (MOQs) typically range from 500 to 2,000 units per specification depending on the customized packaging configuration. Technical evaluation samples are dispatched within 3 to 7 working days. Full mass-production container orders are fulfilled within 25 to 35 calendar days, supported by direct sea freight departures through major ports including Shanghai, Ningbo, and Qingdao.

Comprehensive testing regimes cover every manufacturing phase: dynamic arbor torque tolerance analysis, Rockwell hardness verification across three substrate points, optical micro-measurement of tooth profile geometry, and destructive high-speed cutting trials through standard rebar-embedded concrete blocks or Grade 5 steel screws to evaluate cycle longevity and wear degradation rates. Full inspection documentation accompanies every bill of lading.
