Drill Bit For Metal

Professional Drill Bit For Metal - Precision Engineered Cutting Solutions

Danyang Ebuy Tools delivers enterprise-grade Drill Bit For Metal designed for demanding industrial applications. Our precision-engineered tools feature High-Speed Steel (HSS), M35/M42 Cobalt, and Solid Carbide metallurgy, maintaining cutting edge integrity at temperatures up to 800°C. With our 77,000 square meter facility and 319 skilled employees, we produce 150,000 pieces daily, ensuring consistent quality and reliable supply. Our metal drilling bits deliver precise dimensional tolerances (h8) while maximizing material removal rates across ferrous and non-ferrous substrates, from mild carbon steel to hardened superalloys.

Our Factory

Superior Metal Drilling Performance

Advanced Metallurgical Engineering

Our metal drilling solutions utilize three distinct grade categories. Standard M2 HSS bits offer 63-65 HRC hardness for general applications. M35 Cobalt variants provide enhanced heat resistance with 5% cobalt content and 65-67 HRC rating. Micrograin Carbide options deliver extreme rigidity exceeding 90 HRC for demanding machining environments.

Precision Geometric Design

Each drill incorporates optimized cutting geometry. Point angles vary from 118° for general purpose to 135° split point for self-centering on hard alloys. Helix angles are engineered specifically - Type N for regular applications and Type W/H configurations for soft and hard materials respectively. Parabolic flutes enhance chip evacuation efficiency.

Industrial Applications

Aerospace Manufacturing

Carbide and Cobalt variants excel in machining Titanium (Ti-6Al-4V) and Inconel superalloys. These applications demand exceptional heat resistance and cutting edge stability to prevent work hardening that could compromise component integrity.

Structural Steel Fabrication

M35/M42 Cobalt bits with 135° split points handle I-beam and heavy plate drilling. These tools withstand vibration, misalignment, and heavy feed pressures common in portable magnetic drill applications without chipping or wandering.

Automotive Manufacturing

TiAlN-coated Carbide variants serve high-volume CNC operations on cast iron and aluminum engine blocks. Internal coolant delivery capability enables high RPM operation while maintaining hole straightness over thousands of cycles.

Quality Control Excellence

Dimensional Integrity Testing

Our quality systems employ optical comparators measuring lip height differences within 0.02mm tolerances. We verify concentricity (TIR) and shank diameter precision ensuring secure chucking performance.

Metallurgical Validation

Hardness testing confirms heat treatment depth using Rockwell C measurements. Microstructure analysis verifies carbide distribution uniformity throughout the steel matrix for consistent performance.

Performance Lifecycle Testing

Industry-standard testing involves drilling multiple holes in 4140 alloy steel to measure wear land progression. Each Drill Bit For Metal must maintain cutting efficiency without chatter for specified hole counts before qualification.

Coating Adhesion Verification

Scratch tests ensure PVD coatings (TiN/TiAlN) resist delamination under shear stress. This maintains thermal barrier integrity throughout operational life.

Production Process

Advanced Surface Treatments

Titanium Nitride (TiN) Coating

Provides excellent lubricity reducing friction during cutting operations. Golden color coating offers visual wear indication while extending tool life in general metal drilling applications.

Titanium Aluminum Nitride (TiAlN)

Superior oxidation stability up to 800°C enables dry drilling operations. This coating maintains hardness at elevated temperatures crucial for high-speed machining.

Bright Finish Options

Polished surfaces reduce built-up edge formation especially beneficial for aluminum and non-ferrous metal drilling where galling resistance is essential.

Frequently Asked Questions

Why does my penetrate burn out on stainless steel?

Excessive RPM causes work-hardening. Utilize M35 Cobalt review, diminish speed by 50%, increment nourish weight to cut beneath the solidified surface layer, and apply cutting liquid for ideal results.

What's the distinction between 118° and 135° point angles?

118° focuses suit common gentle steel making longer chips. 135° split-points decrease chisel edge width, empowering self-centering without center punching, cutting more forcefully into difficult alloys.

Can TiAlN coated bits penetrate aluminum?

Not prescribed. TiAlN contains aluminum making chemical liking with workpieces causing irritating or built-up edge. Shinning wrap up or ZrN coatings perform way better on non-ferrous materials.

When ought to I resharpen or supplant my drill?

Inspect the wear arrive on cutting lip external corners. If wear surpasses 0.3mm or web partition happens, torque loads increment hazardously. Regrind HSS/Cobalt bits over 10mm; supplant littler or coated variants.

What advantage does Cobalt offer over standard HSS?

Cobalt augmentations increment ruddy hardness maintenance. This permits cutting edge hardness support at raised temperatures up to 550°C, basic for extreme rough metal penetrating applications.

How do I anticipate bore meandering on difficult metals?

Use 135° split-point geometry dispensing with chisel edge weight. Guarantee legitimate workpiece clamping, utilize center penetrating for gap start, and keep up reliable bolster weight all through the operation.
