Introduction of SF series single-edge drill
The picture on the right shows the typical appearance of the SF series multi-functional single-edge drill bit, which is the representative image of this series of tools.
Also known as Multi-purpose vehicle drilling and boring drill
Material: The cutter body is made of 42CrMo to ensure high strength and durability; the cutting part uses indexable carbide inserts (such as the QCMT series, which offers a variety of coating options), combining economy and excellent performance.
SF series single-edge drill is a composite tool that integrates drilling, face turning, external turning and boring functions. Its processing diameter covers
Φ8mm – Φ25mm (such as SF-8R-2.5D-C20 to SF-25R-2.5D-C32, more specifications can be consulted upon request),
Optimized for completing multiple operations in one clamping on CNC lathes.
Its core advantage lies in "one tool for multiple uses". By reducing the number of tool changes and clamping time, it greatly shortens the processing cycle and reduces costs, thereby maximizing production efficiency.
To address the challenges customers face when machining small-diameter deep holes, such as easy tool breakage, poor chip removal, and difficulty ensuring precision, we have launched a series of high-performance solid carbide single-edge drills.
Structural features:
1. Indexable insert structure
Standard QCMT and other series indexable inserts are available with optional coatings for superior wear resistance.
The inserts feature sharp cutting edges and excellent chip breaking performance, making them suitable for a variety of materials, including steel, stainless steel, and cast iron.
The inserts can be quickly indexed or replaced, and the cutter body is reusable for extended periods, resulting in extremely low unit processing costs.
2. Unique insert structure
The insert is designed with a special geometric shape so that its main cutting edge can complete axial drilling, while the side edge can perform radial turning and boring at the same time.
3. Large spiral groove and internal cooling channel
The cutter body features large chip flutes and a large spiral-flute cutting edge to reduce cutting forces. Combined with internal coolant supply, this ensures smooth chip evacuation and adequate cooling during drilling and turning, effectively protecting the insert and improving machining quality.
Application advantages:
- Multi-function in one: Integrates drilling, facing, external cylindrical turning and boring functions into one tool, greatly shortening the processing cycle and making it suitable for mass production.
- Significant cost reduction: Reduce the number of tool purchases and tool position occupancy, simplify programming and tool management processes, and achieve low overall cost of use.
- Guaranteed precision: Multiple processes can be completed in one clamping, avoiding repeated positioning errors caused by multiple clampings and improving the overall processing accuracy of parts.
- Smooth chip removal: The large helix angle design and large chip groove, combined with internal coolant support, ensure smooth chip removal during continuous processing, especially suitable for long-chip materials and small parameter finishing.
- Easy to use: It can be installed and used as a standard CNC turning tool, without the need for additional special machine tools or accessories, and is easy to upgrade and modify.
Applicable industries:
General precision machinery and parts processing (mass production of standard and non-standard parts such as shafts, sleeves, and gaskets).
Electronics, communications, and heat sink industries: Drilling center holes, flattening end faces, and turning the outer diameters of heat sinks, connector housings, and insulators made of aluminum alloy and copper.
It is widely used in CNC lathes and turning-milling centers. It is particularly suitable for situations where multiple processes such as drilling center holes, flattening end faces, and turning outer circles are required on shaft parts. It is an ideal choice for improving the efficiency of automated production lines.
The recommended matching inserts are the Chuanrun QCMT series (such as QCMT050204, QCMT070304, etc.), which provide a variety of geometry and coating options (aluminum, copper, steel, stainless steel, non-ferrous metals, etc.) to adapt to different processed materials.
The SF series multifunctional single-edge drill provides customers with value solutions that go beyond the tool itself through technological innovation.
It directly targets the core demands of modern manufacturing for efficiency, cost, and precision, and is a powerful tool to help companies achieve intelligent and efficient production.
