What Is a Reduce Milling Point Self-Drilling Screw?

A Reduce Milling Point Self-Drilling Screw is a self-drilling and self-tapping screw featuring a specialized milling point with a reduced cutting profile.

The purpose of the design is to improve the interaction between the drilling point and the metal during installation.

Instead of simply focusing on maximum cutting capacity, the Reduce Milling Point is designed around a balance between:

Cutting Performance + Drilling Speed + Drilling Resistance + Installation Stability

This makes the product suitable for applications where drilling efficiency and controlled penetration are important.

What Is a Reduce Milling Point?

The Reduce Milling Point is a specialized variation of the Milling Point drilling technology.

A conventional self-drilling screw uses a formed drilling point.

A standard Milling Point uses a precision milling-cut process to create the drilling geometry.

A Reduce Milling Point further modifies the cutting profile to reduce the amount of material being removed during the initial drilling process.

The objective is to achieve an efficient drilling action while controlling drilling resistance.

Main Advantages of Reduce Milling Point Self-Drilling Screws

Reduced Drilling Resistance

One of the main reasons to select a Reduce Milling Point is to control the resistance generated during drilling.

A reduced cutting profile can help manage the interaction between the drilling tip and the metal material.

This can be particularly useful when installation equipment and operator efficiency are important considerations.

Efficient Metal Penetration

The milling-cut point is designed to provide an effective cutting action when penetrating metal.

This makes the screw suitable for:

• Steel-to-steel fastening
• Metal panels
• Roofing
• Steel truss
• Thick metal components

The actual penetration capability depends on the material thickness, screw diameter, drilling point, and installation conditions.

Shorter Drilling Time

SANN MUO's Milling Point technology is designed to provide better drilling speed and cutting ability than traditional self-drilling screws. The product family is also described as offering excellent consistency, less pressing force, and shorter drilling time.

For high-volume construction or roofing installation, reducing the time required for each fastening point can improve overall installation productivity.

Which One Should You Choose?

Choose Reduce Milling Point Self-Drilling Screws when the installation process requires controlled drilling resistance and efficient penetration.

Choose No.3 Milling Point Self-Drilling Screws when the primary requirement is strong drilling and cutting performance for metal-to-metal applications.

Reduce Milling Point for Metal-to-Metal Fastening

The primary application of Reduce Milling Point Self-Drilling Screws is metal-to-metal fastening.

Typical applications include:

• Steel-to-steel fastening
• Metal panels
• Sheet metal assembly
• Steel truss
• Roofing systems
• Metal construction
• Thick metal components

The screw can drill and tap the mating metal components in a single installation process.

Reduce Milling Point Roofing Screws

Reduce Milling Point Self-Drilling Screws can be used as self-drilling metal roofing screws when the screw specification is matched to the roofing material and thickness.

Typical applications include:

• Metal roofing
• Corrugated metal sheets
• Roofing panels
• Steel framing
• Steel truss
• Metal-to-metal roofing connections

For roofing applications requiring sealing, the screw can be supplied with an appropriate:

EPDM Washer

or

EPDM Steel Bonded Washer

The washer configuration should be selected according to the roofing material and sealing requirements.

SANN MUO's product category specifically identifies Milling Point products as roofing screws and steel truss applications.

Reduce Milling Point for Steel Truss

Steel truss applications can involve multiple layers of metal or relatively thick steel components.

The Reduce Milling Point is designed to provide controlled cutting action during penetration.

This makes it suitable for applications where the installer needs a combination of:

Fast Drilling + Controlled Resistance + Stable Penetration

Typical applications include:

• Steel truss
• Metal framing
• Structural metal components
• Steel panels
• Roofing structures

Reduce Milling Point for Thick Metal Plate

The Reduce Milling Point product is also positioned for applications requiring good performance in thicker plate.

However, the correct screw should always be selected according to:

• Metal thickness
• Metal hardness
• Number of layers
• Screw diameter
• Drilling point
• Installation tool
• Required drilling time

For particularly demanding thick-plate applications, SANN MUO also offers No.5 Milling Point Self-Drilling Screws, which are specifically positioned for penetration through thick plate up to 12 mm.

Reduce Milling Point vs. No.5 Milling Point

Feature	Reduce Milling Point	No.5 Milling Point
Main Design	Reduced Milling Point	No.5 Milling Point
Main Focus	Reduced drilling resistance	Thick plate penetration
Drilling Speed	Fast	Fast
Pressing Force	Designed for lower force	Less pressing force
Thick Plate	Suitable	Primary strength
Maximum Thickness	Application dependent	Up to 12 mm according to product positioning
Roofing	Suitable	Suitable
Steel Truss	Suitable	Suitable
