Specialized manufacturer of brazed, solid carbide and indexable gun drills expands global supply chain, serving automotive, aerospace, mold, medical and hydraulic industries with custom deep hole tooling
DEZHOU, China – June 29, 2026 — Dezhou Drillstar Cutting Tool Co., Ltd., a leading professional deep hole gun drill manufacturer based in China’s renowned deep hole machining hub Dezhou, officially releases its full portfolio of precision gun drilling tools, catering to surging global demand for high depth-to-diameter ratio deep hole processing. Integrating independent R&D, standardized production and one-stop technical service, Drillstar provides reliable deep hole cutting tools and customized machining solutions for industrial clients across Europe, Southeast Asia, the Middle East and South AmericaDezhou Drillstar Cutting Tool Co., Ltd..
Company Background
Founded in 2013, Dezhou Drillstar focuses exclusively on deep hole machining tooling and supporting CNC gun drilling equipment. The enterprise assembles a technical team of senior cutting tool professors, dedicated R&D engineers and veteran production technicians, owning proprietary manufacturing craftsmanship and complete quality control systems德州钻星刀具有限公司.
Unlike generic cutting tool suppliers, Drillstar specializes in gun drill core production, covering three mainstream gun drill categories with a diameter range of 1.0mm to 65mm, matching all standard and non-standard deep hole machining scenarios. All products undergo strict heat treatment and premium surface coating to boost wear resistance, rigidity and service life under heavy cutting loads.
Core Gun Drill Product Portfolio & Technical Advantages
-
Brazed Gun Drills
Cost-effective single-flute & double-flute welded gun drills for general steel, stainless steel and alloy processing. Optimized chip evacuation flute design eliminates chip clogging, delivering straight hole tolerance and smooth surface finish for mass production lines.
-
Solid Carbide Gun Drills
Ultra-precision monolithic carbide gun drills for micro-deep holes starting from φ1mm. High hardness, excellent thermal stability, ideal for medical parts, fuel injection nozzles and precision mold micro channels, maintaining consistent accuracy at high cutting speeds.
-
Indexable Gun Drills
Replaceable insert gun drills drastically reduce tool maintenance cost. Worn cutting inserts can be swapped without regrinding the entire drill shank, cutting production downtime by over 35% for automotive shaft, hydraulic cylinder and energy equipment manufacturing
All Drillstar gun drills feature internal high-pressure coolant channels, compatible with 6–8MPa cooling systems to realize synchronous cooling and chip removal during deep hole drilling, solving the biggest pain point of overheating and poor surface roughness in deep hole processing.
Industry Application Coverage
Drillstar gun drills are widely adopted for critical deep hole components across key sectors:
- Automotive: Engine connecting rods, fuel injectors, gearbox shafts, hydraulic valve bodies
- Aerospace: High-temperature alloy structural parts, cooling channels
- Precision Mold: Plastic mold cooling holes, die casting deep runners
- Medical Equipment: Stainless steel surgical instrument micro bores
- Heavy Machinery & Hydraulics: Long hydraulic cylinders, oil pipelines
Field test data from global clients verifies that Drillstar gun drills lift overall machining efficiency by nearly 30%, lower workpiece rejection rate by 28%, and extend tool service life by 2–4 times compared with ordinary imported and domestic alternatives德州钻星刀具有限公司.
Customization & Global Service Strength
Beyond standard gun drill specifications, Drillstar supports full non-standard customization: customized drill length, special tip geometry, exclusive coating formulas and matched gun drill holders for special workpieces and hard-to-machine materials (Inconel, titanium alloy, quenched steel).
The company maintains a complete international service system: multilingual technical sales teams provide pre-sales cutting parameter simulation, on-site trial cutting guidance, post-sales tool regrinding and wear analysis service. Products are exported to more than 30 countries, with stable inventory and fast delivery cycles to support overseas manufacturers’ uninterrupted production.
Executive Statement
Ms. Pang Zhanping, Founder & Technical Director of Dezhou Drillstar Cutting Tool Co., Ltd., commented:
“Deep hole drilling has long been a bottleneck restricting precision manufacturing efficiency. For over a decade, Drillstar has centered on solving clients’ actual machining pain points rather than simply selling tools. Our gun drill series balances premium precision and competitive pricing, enabling small and medium-sized factories worldwide to access high-performance deep hole tooling without excessive import costs. We will keep upgrading our carbide grades and tool geometries to meet the evolving demand of high-end intelligent manufacturing globally.”
Future Outlook
In 2026, Drillstar plans to further expand its overseas market layout, participate in major international machine tool exhibitions, and launch upgraded high-feed gun drill series for super-depth hole machining (depth-diameter ratio up to 100:1). The brand aims to build a trusted Chinese deep hole gun drill brand recognized by global precision manufacturers.
