Powermatic CNC hold downs are aluminum arm clamps designed to secure workpieces on CNC setups, giving installers and shop users a dedicated way to keep parts in place during machining. The 1-1/8 inch wide aluminum arm spreads clamping force across more surface area, which helps reduce point pressure on the work and supports more stable cuts. The 5-1/4 inch long arm reaches farther across a part, so you can grip boards or panels past the edge of a T-slot and still keep them stable. The 5/16 inch T-bolt ties the arm into a compatible T-slot or fixture, giving the clamp a positive mechanical connection instead of relying on friction alone. The described set of 2 clamps supports holding more than one point on a workpiece, which improves stability when balancing multiple parts on a CNC table or fixture plate.
The 1-1/8 inch width on each aluminum arm gives you a compact profile that still distributes clamping load, which is useful when laying out several clamps close together on a CNC table. The 5-1/4 inch length creates a useful reach distance from the 5/16 inch T-bolt connection, allowing the clamp to bridge over fixtures or align with the best hold point on the part. The 5/16 inch T-bolt anchors into a T-slot or track-style mounting point, so once the clamp is tightened, it resists sliding as the cutter moves across the work. With two clamps in the set, you can create opposing hold-down points on a single workpiece, supporting more consistent results from run to run.
The PM9-1797000 Powermatic CNC hold downs are designed as clamping arms for CNC work setups, serving as part of the fixturing system that secures material to a table or track. The 1-1/8 inch wide aluminum arm is suited to CNC environments where parts need to be held down without bulky hardware crowding the toolpath. The 5-1/4 inch long arm dimension lets the clamp reach from a T-slot or track toward the interior of a board, so users can secure both edges and interior sections more easily. By tying the arm to the fixturing surface with a 5/16 inch T-bolt, the clamp is suited to tables or jigs that rely on T-slot channels as their main clamping interface. The set of 2 clamps supports clamping both ends of a smaller workpiece or adding an extra hold point on longer stock, keeping the material controlled while the CNC machine runs.
The aluminum arm on each Powermatic CNC hold down provides a balance between strength and manageable weight, which helps installers and operators reposition clamps quickly while still holding parts securely. The 1-1/8 inch width gives each arm a stable stance against the workpiece, which matters when repeated cuts pass near the clamp and small vibrations can loosen narrow-contact hardware. At 5-1/4 inches long, the arm can span beyond the immediate edge of a T-slot, so material that does not sit directly over a slot can still be pulled down firmly for the next run. The 5/16 inch T-bolt serves as the primary anchor, threading into a matching T-slot profile and keeping the clamp from walking under side loads. Using two clamps as described in the set helps distribute holding force along the length of a panel or board, which supports consistent depth and cut quality from one job to the next.
The Powermatic CNC hold downs use aluminum arms that are 1-1/8 inches wide and 5-1/4 inches long, giving a compact clamp that still reaches across a useful area of the workpiece.
The Powermatic CNC hold downs use a 5/16 inch T-bolt, so the clamp arm anchors into a compatible T-slot or track, creating a positive mechanical hold on the fixturing surface.
The Powermatic CNC hold downs use aluminum arms, which keeps the clamp rigid for holding workpieces while remaining lighter for easy repositioning on the CNC table.
The Powermatic CNC hold downs are provided as a set of 2 clamps, allowing users to secure a workpiece at two separate points for better stability during machining.
The Powermatic CNC hold downs use manufacturer part number PM9-1797000, which identifies this specific aluminum arm clamp set for ordering and reference.
The 5-1/4 inch length of the aluminum arm allows the Powermatic CNC hold downs to reach from a T-slot toward the interior of a board, helping clamp material that is set back from the slot.
The Powermatic CNC hold downs from Wurth Baer Supply combine a 1-1/8 inch wide, 5-1/4 inch long aluminum arm with a 5/16 inch T-bolt, giving shops a defined way to secure CNC workpieces to T-slot style fixtures. The PM9-1797000 part number identifies this set of 2 clamps for repeat ordering when you want consistent fixturing across multiple tables or machines. For CNC setups that rely on T-slot anchoring and need low-profile arms to hold material firmly, these Powermatic CNC hold downs provide a focused clamping option built around the stated dimensions and components.
