Dezhou, Shandong, China – May 11, 2026
Dezhou Drillstar Cutting Tool Co., Ltd. (“Drillstar”), a premier Chinese manufacturer specializing in deep hole drilling solutions, continues to lead the industry with its high-performance gun drills. Engineered for exceptional precision, efficiency, and durability, Drillstar’s gun drills address the most demanding deep hole machining challenges across aerospace, automotive, medical, mold, and energy sectors.
The Core Advantages of Drillstar Gun Drills
Gun drills (also known as deep hole drills) are specialized single-flute tools designed for machining holes with extreme length-to-diameter ratios (typically >10:1). Drillstar elevates this classic design with proprietary manufacturing and material expertise:
Rigid & Precision Structure: Featuring a single carbide cutting head, hollow hardened steel shank, and V-shaped external flute, Drillstar gun drills ensure optimal straightness, roundness, and surface finish. Integrated guide pads on the shank provide stable support, eliminating deflection and ensuring consistent hole quality even at great depths.
Through-Coolant System: The hollow shank delivers high-pressure coolant directly to the cutting zone, effectively reducing heat and lubricating the edge. Chips are continuously evacuated through the V-flute, preventing clogging and enabling uninterrupted high-speed drilling (30–100 mm/min) without retraction.
Superior Material & Craftsmanship: Drillstar offers three main gun drill lines:
Solid Carbide Gun Drills: One-piece ground from premium carbide rods, no brazing points, delivering unmatched straightness, stability, and long tool life.
Brazed Gun Drills: Cost-effective single/double-flute designs with carbide heads fused to steel shanks, balancing performance and affordability.
Indexable Insert Gun Drills: Efficient for large diameters, with replaceable inserts reducing operational costs.
Wide Size Range & Customization: Covering diameters from 1.0 mm to 65 mm, Drillstar gun drills accommodate diverse applications. The company also provides non-standard custom solutions tailored to specific workpiece materials (steel, stainless steel, titanium, alloys) and deep hole requirements.
Why Choose Drillstar for Deep Hole Machining?
Located in Dezhou, China’s renowned deep hole machine tool manufacturing base, Drillstar leverages decades of technical accumulation and a professional R&D team (including senior tool experts and experienced technicians). The company adheres to the philosophy of “Tool-Machine Integration, Strict Data Control, Precision First”, ensuring every gun drill meets stringent quality standards.
Compared to conventional drilling methods, Drillstar gun drills deliver:
Higher Precision: IT7–IT9 hole tolerance, excellent straightness (<0.02 mm/m), and superior surface roughness (Ra 0.8–3.2 μm).
Higher Efficiency: 3–5 times faster than twist drills for deep holes, reducing production time and costs.
Longer Tool Life: Premium carbide grades and advanced coating technologies (TiN, TiCN, AlTiN) enhance wear resistance.
Versatility: Ideal for deep holes in fuel injectors, hydraulic components, medical implants, aerospace parts, and mold cooling channels.
Global Reach & Commitment to Innovation
Drillstar’s gun drills and deep hole drilling machines are widely exported to Southeast Asia, Europe, North America, and the Middle East, earning recognition from global manufacturers. The company remains committed to innovation, continuously optimizing gun drill geometries, coolant systems, and material formulations to meet evolving industry demands.
“At Drillstar, we don’t just make gun drills—we engineer solutions for the toughest deep hole machining problems,” said Pang Zhanping, Founder of Dezhou Drillstar. “Our goal is to empower global manufacturers with reliable, high-performance tools that boost productivity and precision.”
