Carbide Drill Overview & Advantages
Built for precision holemaking, our carbide drills combine ultra‑fine grain tungsten carbide, optimized geometries, and application‑specific coatings. They deliver quick penetration, stable chip evacuation, and high hole quality in steels, stainless, cast iron, aluminum, and heat‑resistant alloys. Each tool is ground to sub‑micron accuracy and inspected to ensure consistent performance and long life.
Carbide Drill Types & Applications
General‑Purpose Solid Carbide Bits
A balanced edge design suits carbon and alloy steels and cast iron. It offers repeatable size and dependable starting for daily production.
For Stainless & Heat‑Resistant Alloys
Purpose‑tuned cutting edges and TiAlN/AlTiN coatings control work hardening and wear in austenitic stainless, duplex, Inconel, and titanium. Expect stable tolerances and longer tool life.
Aluminum Drills with Polished Flutes
Polished flutes and sharp rake minimize built‑up edge in aluminum and other non‑ferrous alloys, producing clean, bright holes. Optional DLC coating supports dry or MQL machining.
Deep‑Hole Coolant‑Through (3xD–20xD)
Internal coolant and evacuation geometries stabilize deep‑hole drilling from 3xD to 20xD and reduce pecking. Suitable for aerospace, mold, and automotive components.
Micro (≤3 mm)
Small‑diameter solutions deliver tight runout and precise tolerances for miniature bores in precision parts and electronics.
Key Features & Specifications
Substrate & Coatings
Ultra‑fine Grain Grades
Selected ultra‑fine grain grades with balanced cobalt provide edge integrity, fracture resistance, and thermal stability.
Coating Options (TiAlN, AlTiN, TiSiN, DLC, Diamond)
TiAlN/AlTiN suit steels and high‑temperature alloys. TiSiN increases abrasion resistance. DLC is ideal for aluminum, while diamond coating serves graphite and composites.
Geometry & Accuracy
Point Angles, Split Point, Web Thinning
Optimized point angles (118°/140°/150°), split points, and web thinning reduce thrust, improve centering, and promote smooth chip flow.
Tolerances and Surface Finish
Precision margins and mirror‑like surfaces support roundness and straightness. Diameter tolerance is typically ±0.005–0.010 mm, with h6 shanks.
Size Range & Standards
Dimensions and L/D Options
Metric 0.20–20.00 mm and inch 1/64"–3/4". Available in short, regular, and long series at 3xD, 5xD, 8xD, 12xD, and 20xD with DIN‑compliant cylindrical shanks. Specials on request.
Coolant & Chip Control
Internal Coolant, Flute Polish, Chipbreaker Options
Internal‑coolant designs support high‑pressure delivery. Polished flutes and optional chipbreakers improve evacuation in stainless and aluminum.
Custom Solutions
Tailor‑Made Non‑Standard Designs
We engineer step and form tools, special diameters, and non‑standard lengths to match your hole profile and tolerance targets. Rapid prototyping helps shorten ramp‑up.
Material‑Process Optimization
Substrate, coating, and geometry are tuned to your material, machine, and clamping to improve stability, life, and cost per hole. Send drawings or samples to start.
Manufacturing & Quality Assurance
Advanced CNC Grinding Equipment
Swiss TTB micro centers, WALTER HELITRONIC, DECKEL S22/SRO, and ANCA platforms deliver repeatable sub‑micron grinding accuracy.
Precision Inspection & Presetting
ZOLLER presetting, PG1000 video measurement, and PARLEC systems verify geometry, runout, and edge quality so tools cut to spec from the first hole.
Certifications & Production Capacity
ISO9001 (2023–2026) and SGS certifications, multi‑axis automation, and our Changzhou production base support consistent batches and stable lead times, proven at JIMTOF and Canton Fair.
Toolholding & Compatibility
Collet Chuck Systems & Shrink‑Fit
Pair the drill with high‑precision collet chucks or shrink‑fit holders to reduce runout, improve finish, and extend life.
Presetting and Accessory Support
We provide holder recommendations, length presetting guidance, and compatible accessories to streamline setup and repeatability.
How to Choose the Right Drill
Workpiece & Hole Requirements
Match geometry and coating to material hardness, hole size, tolerance, and finish. Consider spot drilling and exit burr control.
Machine, Clamping & Coolant
Choose non‑coolant or coolant‑through models based on spindle speed, coolant pressure, and fixture rigidity. Rigid clamping reduces runout.
Starting Cutting Data and Support
We offer material‑specific speeds and feeds, peck guidance for non‑coolant setups, and chip control tips to achieve target cost per hole.

FAQs for Carbide Drill
Can a Carbide Drill replace HSS?
Yes. Higher rigidity, heat resistance, and speed capability enable greater throughput and longer life in hard or abrasive materials.
When should I choose coolant‑through?
Use internal coolant for deep holes, heat‑sensitive alloys, or long stringy chips. It stabilizes temperature and improves evacuation.
Can these drills be resharpened?
Most solid carbide designs can be reconditioned. We provide inspection, regrind, and recoating; contact us for a quote.
