DEFA Adjustable Chamfering Tool
Discover the DEFA adjustable chamfering tool, a versatile solution designed to meet the demanding requirements of modern machining operations. From controlled chamfers to enhanced efficiency, here's why the DEFA tool stands out:
Controlled Chamfers, Infinite Adjustments
The DEFA tool empowers machinists with precise control over chamfer thickness across a range of adjustments. With the ability to infinitely adjust chamfering thickness directly on the tool, it offers unparalleled flexibility to accommodate diverse bore dimensions and project specifications. This feature not only enhances precision but also streamlines machining processes by eliminating the need for spindle reversal or workpiece indexing, ultimately saving valuable cycle time.
Versatility for Challenging Materials
Engineered to excel in machining hard-to-machine or highly burr-forming materials, the DEFA tool is an indispensable asset in industries working with exotic materials like Inconel. Its robust construction and advanced cutting system enable front and back chamfering, as well as back-only chamfering of bores, ensuring exceptional performance even in the most demanding applications. This adaptability makes the DEFA tool particularly effective in producing clean, precise chamfers in complex workpieces without compromising efficiency.
Dual Cutting System for Enhanced Efficiency
Equipped with a dual cutting system, the DEFA tool is capable of machining bores with longitudinal grooves, cross-bores, and open bores with discontinuous cuts. This versatility allows for efficient processing of various workpiece configurations, optimizing productivity and reducing setup time.
Premium Materials, Superior Performance
Featuring an exchangeable carbide blade with a material-specific coating, the DEFA tool delivers consistent and reliable performance even in challenging machining environments. Its blade geometry incorporates a sliding surface that enables chamfer cutting without compromising the integrity of the bore surface or thread during penetration, ensuring impeccable surface quality with every operation.

Elevate your machining capabilities with the DEFA adjustable chamfering tool, where precision meets efficiency for machining excellence. Experience the difference and unlock new possibilities in your manufacturing processes.
How Does the DEFA Tool Work?
The DEFA tool operates by cutting a pre-adjusted chamfer diameter with remarkable precision. Its design incorporates blades that are carefully calibrated to maintain a predetermined setting, ensuring consistent chamfer diameters across workpieces. The unique construction of the DEFA blades enables machining in both forward and reverse directions, enhancing versatility in manufacturing processes.
As the DEFA blades engage with the material, the force applied through the feed onto the chamfer definition surface triggers radial retraction along the axis of the chamfered surface. This mechanism results in a gradual reduction in cutting width, allowing for precise control over chamfer dimensions. Crucially, the chamfer angle is determined by the angle of the definition surface, providing flexibility to adapt to diverse project requirements.
Preventing Surface Damage
One of the key advantages of the DEFA tool lies in its ability to safeguard the integrity of hole or thread surfaces during the chamfering process. This is achieved through the ingenious sliding surface geometry of the DEFA blades, which effectively mitigates the risk of damage, ensuring impeccable surface quality.

How Do I Order DEFA?
1. Determine Your Requirements
Before placing an order, it's essential to identify the hole size and chamfer size required for your machining application. Additionally, consider whether you need front & back cutting or back-only cutting blade options for your specific project needs.
2. Consult the DEFA Catalog
Refer to the DEFA catalog to find the minimum hole column, which helps you choose the appropriate tool holder matching your drill hole size. Ensure that the chamfer diameter requirement aligns with the maximum chamfer capacity of the selected tool.
3. Calculate ØD2 Diameter
Calculate the ØD2 diameter (over the blade) by adding 0.080 inches to the ØD (chamfer diameter). This dimension serves as a suffix to the order number, ensuring the precise customization of your DEFA chamfering tool.
4. Specify Additional Features
If you require the tool with an End Plug, add "p" to the order number. Alternatively, leave the field blank if you prefer a tool with a straight shank. This step ensures that your order includes any desired additional features for optimal performance.
By following these steps, you can confidently place an order for DEFA chamfering tools tailored to your specific machining requirements. Experience precision and efficiency in your machining processes with DEFA's high-quality tools designed to deliver exceptional results.
