Product Description

Stainless Steel Hard Thread Drill Bit with Customization and Durability

Product Application:
Specialized tools for creating secure threaded connections in bone or metal during medical procedures and device assembly.

Orthopedic & Trauma Surgery: Self-drilling, self-tapping screws and drill/tap combos for fixation screws in bone without pre-tapping.
Dental & Maxillofacial Implantology: Drill/Tap tools for preparing osteotomy sites and threading jawbone for implants.
Medical Device Assembly: Thread-forming drills for creating strong, chip-free threads in 17-4PH, titanium, or aluminum housings.
Precision Metalworking for Implants: Step and core drills for enlarging holes in hard alloys or creating counterbores for screw heads.

Product Description:
We craft precision thread-forming drill bits and hole-opening tools from hardened 17-4PH stainless steel. These engineered tools combine drilling and threading or prepare holes for threading. For bones, they have optimized flute designs for debris evacuation and thread-forming tips for clean, strong threads. In metal, they act as form drills creating chip-free threads in ductile materials. Made from 17-4PH hardened to ~45 HRC, they offer exceptional wear resistance, staying sharp through multiple uses in abrasive materials. We offer full customization of diameter, pitch, flute length, point angle, and shank type for specific surgical or assembly needs.

Base Material	Alloy & Condition	UNS S17400 / 17-4PH Stainless Steel,Solution Treated & Aged to Condition H900.
	Core Hardness	40-45 HRC(Rockwell C Scale). Provides necessary toughness and wear resistance.
	Key Advantage	Superior to standard HSS, maintains cutting edge integrity when drilling/forming hard tissues and metals.
Tool Design & Types	Type 1: Self-Drilling/Tapping (for Bone)	Combined drill point and tapping threads. Used with self-tapping bone screws.
	Type 2: Drill/Tap (Tap Drill)	Creates pilot hole and cuts threads in bone in two stages (often a stepped design).
	Type 3: Thread-Forming Drill (for Metal)	A form tool that plastically displaces metal to create internal threads (e.g., for implant assembly).
	Type 4: Precision Hole Opener	Core drill or step drill for accurately enlarging an existing hole in metal.
Geometric Specifications	Diameter Range	Bone Tools:1.5mm to 6.5mm (matching common screw sizes). Metal Tools:1.0mm to 10.0mm.
	Thread Pitch (if applicable)	Customizable to match specific screw threads (e.g., 0.5mm, 0.7mm, 1.0mm, 1.25mm).
	Flute Design	Deep, polished flutes for debris evacuation (bone). Optimized for chip-less forming (metal).
	Point Angle	Bone:Typically 70°-90° for precise starting. Metal:118° or 135° split point.
	Shank Type	Straight round, hexagonal (3/8"), or custom surgical drive interface (e.g., quick-connect).
Manufacturing & Precision	Primary Process	CNC grinding from heat-treated blanks. Thread forms are precision ground.
	Dimensional Tolerance	Critical Diameter:±0.01mm. Thread Pitch Accuracy:Meets ISO standards for medical taps.
	Runout (TIR)	< 0.02 mmto ensure concentric cutting and prevent screw misalignment.
Performance & Finishing	Surface Finish	Cutting edges and flutes are finely ground and polished to reduce friction and adhesion.
	Post-Processing	Passivation per ASTM A967 to ensure corrosion resistance.
	Sterilization	Fully compatible with all standard medical sterilization methods (Autoclave, EtO, Gamma).
Quality & Compliance	Inspection	100% dimensional and visual inspection. Functional testing on representative materials.
	Packaging	Individually packaged in protective sleeves, labeled with size and lot number.
	Standards	Can be designed and manufactured to comply withISO 9714(Orthopaedic drilling instruments) and other relevant specifications.
