Why Choose Our Product?
Durable & Efficient
Engineered for tough materials and long-term use, these high-speed steel twist drills are designed to withstand heavy-duty tasks while maintaining performance over time, making them a reliable tool for precision drilling.
Wide Compatibility
These drill bits are versatile and can handle a variety of materials, including metals, alloys, and plastics. Their adaptability makes them a go-to choice for multiple applications across different industries.
Professional-Grade Performance
Perfect for both industrial and DIY applications, these high-speed steel twist drills deliver professional-grade results, ensuring smooth, accurate drilling every time, whether you're working on a large project or smaller, detailed tasks.
Precision Manufacturing
CNC grinding ensures precise flute and point geometries, providing stable and accurate drilling. Vacuum heat treatment delivers uniform hardness, enhancing long-lasting performance. The polished surface reduces friction, promoting smooth chip evacuation and minimizing thermal stress during drilling.
Purified Steel Composition
Advanced smelting techniques (EAF + LF + VD + RS ESR) produce ultra-clean steel, providing superior toughness. This reduces the risk of fracture and ensures reliability in demanding operations.
Optimized Hardness & Toughness
Through a cycle of quenching, cryogenic treatment, and tempering, the drill bits achieve up to HRC 67 hardness while maintaining structural integrity. This makes them ideal for drilling tough materials, with enhanced strength and durability.
Enhanced Cutting Edge Durability
RS ESR technology improves the distribution of abrasive grains, increasing wear resistance and heat tolerance. This ensures exceptional performance, particularly in deep-hole applications where prolonged use and heat build-up are common.
Tailored Configurations
Available in multiple HSS grades including M2, M35, and M42, these drill bits are designed for specific material types. Customizable options include flute lengths, helix angles, and coatings such as TiN and TiAlN, tailored to meet various machining needs and maximize cutting efficiency.
Key Adaptations for Twist Drills:
Optimized Flute Geometry
The flute geometry is designed to enhance chip removal, minimizing heat buildup and ensuring smooth operation, even during high-speed or deep-hole drilling.
Customizable Performance Features
Point and helix angles can be tailored to optimize performance for specific materials, ensuring precision and efficiency during drilling.
Versatile HSS Grades
Offered in popular grades like M2, M35, and M42, these drill bits come with optional coatings (TiN, TiAlN) for added durability and improved cutting efficiency in demanding environments.
Q1: What materials and coatings are available?
Our drills are made from high-speed steel grades like M2, M35, cobalt-enriched HSS, and PM-HSS. Coating options include:
TiN (Titanium Nitride): General use for wear resistance.
TiAlN (Titanium Aluminum Nitride): For high-heat applications.
TiCN (Titanium Carbonitride): For better surface hardness.
Uncoated versions are also available. These coatings help extend tool life, especially for tough metals like stainless steel or titanium.
Q2: What causes early tool failure?
Common causes include:
Too high feed rates or speeds.
Lack of cooling or lubrication.
Using the wrong drill for the material.
If damaged outside of user error, tools may qualify for replacement. Our support team is available for help.
Q3: When should a drill be replaced?
Replace the drill if you notice:
Excess burrs or irregular cutting sounds.
Dimensional changes over 0.1 mm.
Visible chipping or wear on the edge under magnification.
Q4: How is the helix angle selected?
30°-35°: For steel and cast iron.
40°-45°: For aluminum and softer metals.
10°-20°: For hardened materials, minimizing vibration.
Q5: Are custom geometries available?
Yes, we offer custom options like:
Internal coolant channels (requires a drawing).
Stepped profiles and multi-land edges for specific needs.
