This detailed product description presents the Wieländer+Schill part number 617241, 100° countersink flat cutter, which features an integrated depth stop and pilot. This tool is an indispensable device for creating the countersunk holes required for precise screw and rivet fastenings, especially in the fields of automotive body repair and metalworking.
The 100° countersink flat cutter is made from high-quality HSS (High-Speed Steel) material, which guarantees a long service life and excellent cutting performance on various metal materials. The main function of the tool is to create perfectly fitting, flat countersinks that allow the screw heads or rivet heads to be placed flush with or slightly below the material surface.
The outstanding feature of the product is the integrated depth stop and pilot (guide pin). The pilot ensures the precise positioning of the cutter in the center of the existing hole, preventing the tool from slipping on the workpiece. The depth stop, in turn, guarantees that every countersink has the same depth, which is critically important for standard-compliant, aesthetic, and functional fastener installation.
This tool belongs to the Wieländer+Schill category „Separating Tools,” specifically within the „Drilling Tools” subcategory, intended expressly for precision preparation work.
Precision Countersinking: The 100° angle is ideal for most standard screw and rivet heads, ensuring a perfect fit.
Integrated Guiding System: The pilot pin has a diameter of 6.6 mm, which accurately centers the tool in the hole.
Controlled Depth: The depth stop function prevents excessive material removal, thus guaranteeing consistent results.
Excellent Material Quality: HSS (High-Speed Steel) construction for durability and efficient material removal.
High Rotational Speed Compatibility: Can be used at a maximum speed of 3000 revolutions/minute, enabling fast operation.

This countersink tool is an ideal choice for the following areas:
Automotive Body Repair: Especially useful in body repair work where screws or rivets need to sit flush with the surface (e.g., fastening repair plates).
Assembly of metal structures: Creation of precise countersinks for screwed or riveted connections.
General Machining Operation: Any application where the hole inlet side must be conically shaped to receive the fastener.
For maximum efficiency and flexibility, the following accessory products are recommended for the 100° countersink, which can be purchased separately:
Part number: 617243
Description: Basic 100° countersink, which can also be used independently if the centering provided by the pilot drill is not required. Ideal for existing, precisely drilled holes.
