Product Description

Custom Threaded Drill Bit for CNC Milling and Hard Thread Applications

Product Application:
Specialized self-tapping tools for secure, high-integrity threaded connections in bone or metal during medical procedures.

Orthopedic & Trauma Surgery: Self-drilling, self-tapping screws for fixation in cortical/cancellous bone.
Dental & Maxillofacial Implantology: Drill/Tap tools for osteotomy sites and jawbone threading for implants.
Medical Device Assembly: Thread-forming drills for chip-free internal threads in 17-4PH, titanium, or aluminum.
Precision Metalworking for Implants: Step/core drills for enlarging holes in alloys or creating counterbores for screws.

Product Description:
Precision thread-forming drill bits from 17-4PH stainless steel, combining drilling and threading. For bone, optimized flutes evacuate debris; for metal, form threads without chips. Tools made from 17-4PH, hardened to ~45 HRC, ensure wear resistance and durability. Fully customizable to match surgical/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.
