Product Application:

These are specialized self-tapping and hole-preparation tools designed for creating secure, high-integrity threaded connections directly in bone or metal during medical procedures and device assembly.

• Orthopedic & Trauma Surgery: Self-drilling, self-tapping bone screws and the corresponding drill/tap combos for placing fixation screws in cortical and cancellous bone without pre-tapping.

• Dental & Maxillofacial Implantology: Drill/Tap instruments for preparing osteotomy sites and forming threads in the jawbone for dental implants.

• Medical Device Assembly: Thread-forming drills (form taps) for creating strong, chip-free internal threads in 17-4PH, titanium, or aluminum housings and components of implantable devices.

• Precision Metalworking for Implants: Step drills and core drills for accurately enlarging pre-drilled holes in hard metallic alloys prior to tapping or for creating counterbores for screw heads.

Product Description:

We manufacture precision thread-forming drill bits and hole-opening tools from hardened 17-4PH (H900 condition) stainless steel. These are not standard twist drills; they are engineered tools that combine drilling and threading actions into one operation or precisely prepare a hole for subsequent threading. For bone applications, they feature optimized flute designs to evacuate bone debris efficiently and specific thread-forming geometries on the tip to cut clean, strong threads in bone. For metal machining, they act as form drills that displace material to create threads without generating chips, resulting in stronger threads in ductile materials. Made from 17-4PH hardened to ~45 HRC, these tools offer exceptional wear resistance and durability, maintaining sharpness through multiple uses in abrasive or tough materials. We offer full customization of diameter, pitch, flute length, point angle, and shank type to match specific surgical or assembly requirements.
