1.Product Specification
This 4PCS Cross Hammer Drill Bit kit adopts standard SDS Plus four-groove shank design, perfectly matching all SDS Plus rotary hammer drills for construction drilling work. The Cross Hammer Drill Bit features four hard alloy cross cutting tips, delivering stable cutting force and fast debris removal during heavy impact drilling. The Cross Hammer Drill Bit undergoes full sandblasting surface treatment, with excellent wear resistance and anti-rust performance to adapt to dusty, damp construction sites. The Cross Hammer Drill Bit is manufactured with thickened spiral double flutes, which quickly discharge cement and stone dust without clogging the drilling hole. This Cross Hammer Drill Bit set contains four mainstream sizes: 6mm, 8mm, 10mm, 12mm, all with unified 160mm total length to meet daily renovation and engineering punching demands. Every Cross Hammer Drill Bit passes strict hardness inspection and impact testing before delivery to guarantee long service life under continuous heavy use.

2.Craft & Performance
The Cross Hammer Drill Bit is forged from high-strength alloy steel with integrated forming craft, effectively resisting bending and fracture under high-frequency impact hammering. The four-cutter cross hard alloy tip of the Cross Hammer Drill Bit is firmly welded at the drill head, boasting ultra-high hardness to break concrete and brick quickly without chipping or dulling easily. Double thickened spiral flutes on the Cross Hammer Drill Bit expand the chip removal space, so stone and cement residues can flow out smoothly during continuous deep drilling to avoid hole blockage. The SDS Plus four-slot shank of the Cross Hammer Drill Bit locks tightly with the hammer drill’s internal transmission structure, transmitting full impact power without slipping or energy loss during long-hour construction. Sandblasted matte surface of the Cross Hammer Drill Bit forms a dense protective layer, preventing rust and surface abrasion caused by cement powder and moisture. The uniform spiral pitch design keeps the Cross Hammer Drill Bit rotating stably without deviation, creating neat round holes and reducing secondary trimming work after punching.
Application
The durable Cross Hammer Drill Bit is widely used in residential renovation, engineering construction, electrical installation and pipeline laying projects. It performs outstanding drilling effects on reinforced concrete, hard rock, solid cement walls, red brick walls and stone masonry. The Cross Hammer Drill Bit is the essential punching tool for installers of water pipes, electrical conduits, curtain walls and wall-mounted hardware. Whether drilling small holes for expansion screws or medium deep holes for pipeline embedding, the Cross Hammer Drill Bit maintains stable penetration speed and smooth chip removal. For professional construction teams and DIY home renovators, this 4-size Cross Hammer Drill Bit set covers most common wall punching scenarios, replacing multiple single-size drill bits and improving overall construction efficiency significantly.
