Product Description

Product Name:
Solid Carbide 3-20mm Diameter Internal Coolant Twist Drill Bits for Steel, Cast Iron, Stainless Steel, and Titanium Alloys

Product Description:
Our Solid Carbide 3-20mm Diameter Twist Drill Bits are engineered for high-performance machining and precision drilling. These drill bits feature internal coolant channels to provide efficient cooling during operation, which is essential for maintaining cutting tool performance and extending tool life. The solid carbide construction ensures exceptional hardness, wear resistance, and the ability to handle high-speed drilling, making them ideal for machining a wide range of materials, including:

• P-class steel materials
• K-class cast iron
• M-class stainless steel
• S-class heat-resistant alloys, including titanium alloys

With a diameter range from 3mm to 20mm, these drill bits offer versatility for different drilling applications, whether you are working with soft steels, hard stainless steel, tough cast iron, or challenging heat-resistant alloys like titanium. The internal coolant system ensures better heat dissipation and improved surface finishes, helping reduce the chances of drill bit wear and extending tool life.

 

Key Features:

• Internal Coolant Channels: Designed with internal coolant passages to improve cooling during drilling, reducing heat build-up, enhancing tool life, and increasing drilling efficiency.
• Solid Carbide Construction: Made from solid carbide for maximum hardness and durability, capable of withstanding high drilling speeds and providing precise, clean holes.
• Wide Material Compatibility: Perfect for machining P-class steel, K-class cast iron, M-class stainless steel, and S-class heat-resistant alloys, such as titanium alloys.
• Precision Drilling: The drill bits are engineered for high precision and excellent surface finish, making them suitable for demanding applications.
• Diameter Range (3-20mm): Available in a broad range of diameters to accommodate various drilling requirements.
• Versatile Applications: Ideal for use in CNC machines, manual lathes, and drilling machines for a wide range of applications, from general industrial use to specialized machining.

 

Applications:

• Steel Machining (P-class): Excellent for drilling precision holes in carbon steels and alloy steels, offering a smooth and efficient drilling process.
• Cast Iron Machining (K-class): Ideal for drilling cast iron components in automotive, aerospace, and manufacturing industries.
• Stainless Steel Machining (M-class): Perfect for working with stainless steel alloys, offering superior wear resistance and cutting power.
• Heat-Resistant Alloys (S-class): Highly effective for drilling tough materials like titanium alloys and nickel-based superalloys commonly used in the aerospace and medical industries.
• General Precision Drilling: Suitable for high-precision applications requiring minimal hole distortion and tight tolerances.

 

Advantages:

• Improved Cooling: The internal coolant system reduces friction, dissipates heat, and prolongs the life of the drill bit while improving surface finish.
• Extended Tool Life: Solid carbide material ensures high resistance to wear, allowing for longer tool life even in demanding drilling conditions.
• Versatile Material Compatibility: Ideal for drilling a broad range of materials, including steels, cast irons, stainless steels, and heat-resistant alloys.
