Customization Of 17-4PH Stainless Steel Medical Hard Thread Drill Hole Opener

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.

Product Technical Parameters:

Category	Parameter	Details / Specification
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 mm to 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 with ISO 9714 (Orthopaedic drilling instruments) and other relevant specifications.
