90° Carbide Chamfer Mill Overview

This 90° solid carbide chamfer mill is designed for precision spotting, edge chamfering, countersinking and hole-preparation operations on CNC machining centers. The pointed 90° cutting profile can establish an accurate starting position before drilling while also producing controlled chamfers around drilled holes and machined edges. Micro-grain solid carbide construction provides rigidity and wear resistance for repeated production use. Reference configurations cover Ø1–Ø20 mm cutting diameters, with compact standard lengths and selected 100 mm and 150 mm long-reach options available for different machining setups.

90° Multi-Purpose Cutting Configuration

90° Point Geometry

The symmetrical pointed profile supports accurate spotting before drilling and controlled 45° chamfers on each side of the included 90° angle.

Hole-Preparation Capability

One tool can be used for spotting, hole-edge chamfering and selected countersink or counterbore-style preparation, reducing unnecessary tool changes in suitable applications.

Size-Specific Flute Design

Small diameters use compact 2-flute configurations, while larger reference sizes use 3 flutes to provide additional cutting-edge support and stable chamfering performance.

Application-Specific Advantages

90°

Controlled Chamfer Geometry

The fixed 90° included angle supports repeatable hole-edge and external-edge chamfering.

◎

Accurate Spotting

The pointed cutting profile establishes a defined starting location before subsequent drilling operations.

2/3F

Stable Cutting Engagement

Two- and three-flute configurations are matched to the reference diameter range and tool proportions.

OEM

Flexible Size Options

Cutting diameter, angle, shank and overall length can be reviewed for standard or non-standard applications.

Recommended Machining Operations

The 90° chamfer mill is intended primarily for hole preparation and edge-finishing operations. Final cutting conditions should be matched to the workpiece material, tool diameter, chamfer width, machine rigidity and holder runout.

Hole Spotting
RECOMMENDED
90° Chamfering

Operation Note:
Control axial depth carefully because chamfer diameter increases with cutting depth on a 90° profile. Use low runout and stable toolholding when spotting small holes or producing precision chamfers.

Chamfering & Spotting Application Guidance

  • Chamfer Depth: Control axial position carefully because a small depth change directly changes the finished chamfer diameter.
  • Spotting: Use a stable, low-runout setup to maintain accurate hole location before the following drilling operation.
  • Tool Overhang: Use the shortest practical extension whenever possible, especially with long 100 mm or 150 mm configurations.
  • Toolholding: Use a clean precision collet or holder and verify radial runout before machining small-diameter features.
  • Material Selection: Match carbide grade, edge preparation and coating to the workpiece material and hardness rather than using one configuration for all materials.

Product & Application FAQs

Answers to common questions about selecting and applying the 90° Solid Carbide Chamfer Mill for spotting, chamfering, countersinking, hole-edge preparation and selected counterbore-style machining.

What operations is this 90° chamfer mill designed for?
The 90° cutting profile is designed primarily for spotting, hole-edge chamfering, countersinking, deburring and selected recess-preparation operations. It can combine several hole-preparation steps when the same angle and cutting geometry are suitable for the required feature.
Can this chamfer mill be used for spotting before drilling?
Yes. The pointed cutting profile can establish a defined starting position before the following drilling operation. For precision spotting, use a low-runout setup and confirm that the spotting angle is suitable for the geometry of the drill used in the next operation.
Can this tool be used for counterboring?
It can be used for selected counterbore-style or recessed hole-preparation features where the cutting profile matches the required geometry. For a true flat-bottom counterbore, the bottom profile and end-cutting geometry should be confirmed from the component drawing before production.
How is the final chamfer diameter controlled?
The finished chamfer diameter changes with axial cutting depth on a 90° profile. Consistent Z-axis positioning, workpiece height control, holder condition and tool runout are therefore important when producing repeatable chamfer dimensions.
Why are both 2-flute and 3-flute versions available?
Selected small-diameter models use a 2-flute configuration to provide practical chip space around the compact cutting point, while larger reference sizes use 3 flutes for additional cutting-edge engagement and stable chamfering performance.
What should be considered when using long-reach versions?
Extended 100 mm and 150 mm configurations provide additional access but reduce overall rigidity compared with shorter tools. Use the shortest practical overhang, a precision holder and controlled cutting engagement to limit vibration and maintain chamfer accuracy.

Ordering & Customization FAQs

Information for distributors, tooling suppliers and industrial customers requesting standard or application-specific HY chamfer mill configurations.

What standard sizes are available?
Reference configurations cover cutting diameters from Ø1 to Ø20 mm, with shank diameters and total lengths matched to the selected model. Standard lengths range from compact 50 mm versions to selected 100 mm and 150 mm extended configurations.
Are angles other than 90° available?
Yes. The 90° configuration is the primary option on this product page, while selected diameters can also be supplied with 60° or 120° included angles. The required angle should be confirmed according to the spotting, chamfering or countersinking feature.
Can non-standard dimensions or cutting geometry be customized?
Yes. Cutting diameter, included angle, flute configuration, shank diameter, overall length and selected cutting-edge geometry can be reviewed according to the workpiece material, component drawing and machining requirement.
Can coating be selected according to the workpiece material?
Yes. Carbide grade, edge preparation and coating can be reviewed according to the workpiece material and hardness. Steel, stainless steel, hardened steel and non-ferrous materials may require different configurations rather than one universal coating.
Are OEM marking and private-label packaging available?
Yes. Laser marking, customized tool codes, private labels, individual protective tubes and packaging options can be reviewed according to the available shank marking area, packaging specification and order quantity.
Thời gian thực hiện thông thường là bao lâu?
When available from stock, standard items are generally ready for shipment within 1–3 working days. Lead time for customized tools is confirmed after specification and quantity review.
What information is required for an accurate quotation?
Please provide the workpiece material and hardness, cutting diameter, included angle, shank diameter, overall length, flute preference, required chamfer or recess geometry, machining depth, coating preference and order quantity. A tool drawing or component drawing is recommended for non-standard applications.
