Why choose our high-performance chamfer mills?

JINOO chamfer mills are designed to achieve high-precision edge finish. With optimized angle geometry and an ultra-rigid structure, our chamfer mills can provide high-quality chamfering and stable machining. Besides, chamfer mills can deliver consistent angle dimensions and superior surface quality.

Micro Grain Material

Our chamfer mills use ultra-micro grain material, with a grain size ranging from 0.4 to 0.6 μm. Different carbide grades are available for steel and aluminum.

Advanced Coatings

We apply advanced nano coatings for chamfer mills, including AlTiN, AlTiSiN, and DLC coatings. Customized coating solutions are also available.

Precision Angle Geometry

Manufactured with high-precision technology, our chamfer mills can provide various accurate angles, including 60°, 90°, and 120°.

Sharp Cutting Edge

The cutting edge uses precise grinding technology and has sharp cutting geometry. This design is widely used for chamfering, deburring, and spot drilling.

High Rigidity Structure

With a 3-flute structure, our chamfer mills have large core diameters and deliver high rigidity.

Short Flute Design

A short flute design can reduce overhang length and provide a high-rigidity structure for high-precision chamfering.

Technical details of our high-performance chamfer mills

Micro Grain Material for Wear Resistance

0.4–0.6μm ultra-micro grain delivers high hardness over HRA92.5. They help chamfer mills balance wear resistance and toughness. Our chamfer mills are suitable for both continuous and interrupted cutting.

Advanced Coatings for Long Tool Life

For steel machining, we use AlTiN and AlTiSiN coatings with excellent oxidation resistance. For aluminum machining, we use DLC coatings with low friction.

Precision Angle Geometry for Accurate Chamfer

The precise angle design, including 60°, 90°, and 120°, ensures consistent chamfer dimensions and countersink quality.

Sharp Cutting Edge for Smooth Surface

Sharp cutting edges reduce cutting force, improve deburring performance, and ensure smooth surfaces.

High Rigidity Structure for Stable Performance

Compared with 2-flute end mills, the 3-flute design maintains sufficient chip space and enhances core diameter. High-rigidity structures can reduce vibration and improve surface quality in high-speed chamfering.

Short Flute Design for Low Vibration

The flute length is optimized for reducing tool deflection and improving machining accuracy. A short flute structure can enhance rigidity and cutting efficiency.

FAQ about Chamfer Mills

Does JINOO provide customized services for chamfer mills?

Of course! JINOO provides customized services for chamfer mills. We can optimize tool geometry according to your actual machining demands.

Specification Customization

We can customize tool specifications, including diameter, flute length, overall length, chamfer angle, coating type, and shank dimension.

Geometry Optimization

Our engineering team can optimize geometry based on chamfer angle, deburring demands, and different materials.

Application Support

For complex machining conditions, we can provide cutting plans for you to ensure our chamfer mills perform well in your actual machining conditions.

What is your MOQ (Minimum Order Quantity)?

For standard chamfer mills, we have a minimum order quantity of only 1 piece.
For customized end mills, the MOQ depends on specific tool design and dimensions.

What is the lead time for chamfer mills?

For standard chamfer mills, the lead time is typically 5 to 12 working days. Due to the premium carbide rods being shipped from Germany.
The lead time of customized chamfer mills depends on the specific design and our company’s production schedule. We will offer you a clear delivery time after confirming the customization plan.

Does JINOO provide chamfer mill samples?

Yes. We can provide paid samples for you.
You can test cutting performance, stability, and the life of our chamfer mills. Through the trial, you can judge whether the sample is suitable and reduce the risk of tool selection.

What are the shipment and payment methods for chamfer mills?

For Shipment:

JINOO supports both air freight and sea freight.
We cooperate with international logistics companies, including FedEx, DHL, and UPS, ensuring timely delivery of our chamfer mills.
Our carbide milling cutters will be protected by shockproof and waterproof packaging. We can arrange delivery flexibly according to the urgency of orders.

For Payment:

We support common payment methods, including bank transfer, credit cards, and PayPal.
Additionally, we can also adjust the payment terms through consultation.

How to choose a suitable chamfer angle for machining?

The selection of chamfer angles depends on workpiece material and machining requirements.

60° chamfer mills: Fine deburring & Small edge chamfering

Suitable for small chamfer widths and high-precision edge finishing.
Widely used for machining aluminum parts, electronic parts, and precision components.
Low material removal rate, but smoother edge transition.

90° chamfer mills: General machining & Industry standard

The most common chamfer angle in CNC machining.
Suitable for deburring, countersinking, and assembly edges.
Balances stability, tool life, and precision.

120° chamfer mills: Heavy edge preparation & Reduced force

Suitable for large chamfer widths and stronger edge breaking.
Reduces cutting force in machining steel and hardened materials.
Ideal for heavy-duty chamfering before secondary machining.

What is the difference between chamfer mills and end mills?

Both chamfer mills and end mills can be used for chamfering, but their performance and applications are different.

Chamfer Mills: Dedicated edge finishing tool

Designed for chamfering, deburring, and countersinking.
Fixed-angle geometry ensures high chamfering consistency.
Short flutes and high-rigidity structure improve machining stability.
Tool path is simple and direct, reducing progression difficulty.
Suitable for mass production.

End Mills: General milling tool & Chamfering by programming

Designed for slotting, pocket machining, and 3D contouring.
Chamfering is achieved by programming, not a fixed angle.
Chamfering accuracy highly depends on programming and operator skill.
High risk of inconsistent dimensions and increased burrs in mass production.
Tool wear affects chamfer quality.

So, JINOO chamfer mills are the better choice for high-quality machining.

Why do chamfer mills produce burrs, and how to avoid them?

The reason for burrs production in chamfering lies in improper cutting methods.

Here are some possible reasons:

The milling tool is not sharp, so the material is squeezed rather than cut.
The feed rate is low and produces too much friction.
The chamfer angle is not suitable for specific materials.
The direction of the chamfer mill is inaccurate.

Solutions:

Ensure a sharp cutting edge, especially for aluminum machining.
Improve feed rate and avoid squeezing.
Optimize the chamfer mill machining path and reduce the burr of milling cutters.

What flute count is best for chamfer mills?

You should consider material and working conditions when choosing flutes.

2-Flutes: suitable for aluminum machining, with smooth chip evacuation and anti-adhesion.
3-Flutes: suitable for general machining, keeping a balance between rigidity and chip removal.
4-Flutes: suitable for steel machining, with high rigidity and excellent stability.

Unlike rough end mills, the cutting depth of chamfer mills is small. So, the flute count influences surface quality, stability, and tool life.

You can choose 3 flutes or 4 flutes for high-precision edge control to ensure stability.
