Product Description
Product Description
Through-Coolant Drill for Hole Machining
In modern precision machining, efficient hole-drilling—especially for high-hardness materials like alloy steel, stainless steel, and titanium alloys—demands tools that balance speed, accuracy, and tool life.
Our Through-Coolant Drill (also known as "spray drill" for hole machining) redefines performance standards by integrating advanced material science with innovative coolant delivery technology, solving core pain points such as chip clogging, excessive tool wear, and poor hole surface finish in traditional dry or external-coolant drilling.
Whether you're producing automotive engine components, aerospace fasteners, or precision molds, our Through-Coolant Drill delivers reliable performance, cost savings, and consistent quality—making it the ideal choice for modern high-efficiency hole machining.
KEY FEATURES & SPECIFICATIONS
Heat-Treated Alloy Steel Construction
Built from high-grade forged steel with advanced heat treatment for exceptional durability and dimensional stability under extreme conditions.
Precision Ground Surfaces
All critical surfaces are machined to tight tolerances (±0.0004" T.I.R.), ensuring optimal concentricity and minimal runout during rotation.
Corrosion-Resistant Finish
Industrial-grade surface treatment prolongs service life and withstands coolant exposure.

FAQ
Q1: What information do I need to provide to get the right CNC tool recommendation?
A: Please share 4 essential details:
1. The material of your workpiece (e.g., aluminum 6061, stainless steel 304);
2. Machining operation (e.g., milling, turning, threading);
3. CNC machine model (if known, e.g., FANUC 0i-MF);
4. Required precision (e.g., ±0.01mm). This helps us match tools that fit your needs perfectly.
