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.

Q2: How long will it take for my CNC tool order to be delivered?

A: For stocked items, we ship within 1-2 working days. Delivery time depends on your location: 2-3 days for domestic first-tier cities, 5-7 days for remote areas. For custom tools (e.g., non-standard carbide cutters), production takes 7-10 working days plus shipping time. Tracking provided upon shipment.

Q3: What payment methods do you accept for CNC tool orders?

A: We offer a variety of secure payment methods:
1. Bank transfer (our bank details provided);
2. Online payment platforms (e.g., Alipay, WeChat Pay domestically; PayPal internationally);
3. 30% advance on large orders (≥10,000 yuan), balance before shipment.

Q4: Can CNC tools be returned or exchanged if they don't fit?

A: Yes, under certain conditions:
1. Tools must be unused, with no edge scratches, and in original packaging;
2. Request return/exchange within 7 days of receipt;
3. Return shipping at your cost; we send correct tools upon receipt. Customized tools are non-returnable unless defective.

Q5: Are discounts available for bulk CNC orders?

A: Certainly! Bulk purchases include:
1. 5-10% off for 100-500 inserts or 50-100 holders;
2. 10-15% off for over 500 inserts or 100 holders;
3. Additional annual rebates for long-term partners. Contact sales for quotes.

Q6: How to check my CNC tool order status?

A: Two convenient ways:
1. Log into your account on our website (for online orders) – real-time status updates;
2. Call customer service or email your order number – we'll provide the latest status (e.g., "Shipped on Oct 12, tracking: SF123456789").

Q7: What if the CNC tool has a quality issue (e.g., chipping)?

A: Capture photos/videos of the defect and machining scene, send to after-sales within 3 days. We'll evaluate:
1. If due to manufacturing, we send a free replacement, covering shipping;
2. If due to misuse (e.g., incorrect cutting parameters), we provide technical advice.

Q8: Do you offer technical support for CNC tools?

A: Yes, complimentary technical support available! You can:
1. Call our technical hotline – our engineers assist with cutting parameters (e.g., speed, feed rate for aluminum); 2. Request on-site guidance (orders over 20,000 yuan) – our technician adjusts settings at your factory;
3. Access our online resource center (videos, manuals) for usage guidance.

Q9: Can you ship CNC tools to overseas customers? What about customs clearance?

A: We ship to over 50 countries including USA, Germany, and Japan. For international orders:
1. We provide essential commercial invoices and packing lists for smooth customs clearance.
2. Opt for your ideal shipping method—DHL, FedEx, or sea. DHL delivers in 3-5 days, sea freight in 20-30 days.
3. Import duties and taxes fall on the customer. We'll help estimate costs prior to shipping.

Q10: What's the warranty period for your CNC tools?

A: Warranty varies by product type:
1. CNC inserts have a 3-month warranty, covering manufacturing defects (not normal wear);
2. Carbide end mills and tool holders have a 6-month warranty for cracks or deformities not from misuse;
3. High-precision hydraulic holders feature a 12-month warranty. Keep your order invoice for warranty proof.
