Diamond Parting Tool

Guidelines shown below are for use with the Tormek SVS-50 Multi Jig. For the Diamond Parting Tool, the Open Seat is used.

The 3D-printed jig is designed to ensure the parting tool is held perpendicular to the universal support bar. Below are links to the STL files used to 3D print this. The file needed is based on the side angles (γ) as outlined in the picture to the right.

General Guidelines
β	JS	P	TTS-100 Hole	Jig	Comments
65°	n/a	60 mm	B	3D-Printed Jig	End View of the tool β can range from 50° - 85°. It is recommended to not move side-to-side with the tool's edge engaged with the grinding surface, especially when using the SVS-50. Instead, move to a position, ensure the SVS-50 is engaged fully with the USB, and then raise the handle to engage the tool with the grinding surface. If you want to move use a different part of the grinding surface, lower the handle first, and then repeat the above-listed instructions.

Notes & Comments

Information regarding Grindstones

Edge Profile	Comments
	This is the shape for the tool when shipped by most manufacturers. The edges may be flat instead of slightly concaved (shown exaggerated here).
	This shape has a convex edge on the bottom edge. Advantage Disadvantage The added metal below the center line provides better support for the cutting edge, reducing vibration at the tip. This shape does not burnish the wood as quickly as the traditional shape. The tool is kept sharp longer. This shape will not be as sharp (as the β will be larger). This tool shape cannot be flipped to allow the turner to use the the other side. This is useful when wood builds up on the edge's surface (as it does with oily woods like padauk). It also does not allow for usage in as close a quarter (i.e., when using the tool like a bedan to cut at a rotated angle).
