Tog-L-Loc Tooling

Note: The information contained on this page is for standard tooling - custom solutions are available. Contact BTM for more information.

There are two primary components to the Tog-L-Loc clinching process: a punch, and a die. These patented tools are specially designed to clinch sheet metal without piercing it- creating a strong, circular; leak-proof joint.

There are currently six standard Tog-L-Loc tool sizes: 3.0mm [.12"], 3.8mm [.15"], 4.6mm [.18"], 5.5mm [.22"], 6.4mm [.25"], and 7.6mm [.30"]. Tog-L-Loc tool size is measured from the punch tip diameter.

Choosing the correct tool size for an application depends on factors such as the type and thickness of the materials being joined, the amount of space that is available to make a joint, and the desired amount of strength that a joint should have. This information is typically resolved during sample joining at BTM.

Tog-L-Loc Punches



Tog-L-Loc punches feature a slight radius around the tip which allows the punch to control the lateral flow of the sheet metals without piercing or lancing them. The appropriate "Punch Tip Radius (PTR)" for an application is determined through testing at BTM. Standard Tog-L-Loc punches are available in three basic mounting configurations:

	940 Style Mounting (Preferred) This punch style features a spherical washer designed to precisely locate the punch and provide an easy means of extracting it from a holder.
	Ball Lock This punch uses a ball and a spring as its retention method.
	Whistle Notch Flat This punch uses a set screw as its retention method.

Tog-L-Loc Punch Holders

BTM manufactures standard punch holders in three basic styles: Round Holders (for die set mounting), Shank Holders, and Thin Holders.*

	940 Series (Preferred) Dies in this series feature three moving blades surrounded by a built in die shield.
	Three Blade Elastomer Series Dies in this series feature three moving blades surrounded by an elastomer. These dies are ideal in tight joining locations where the die guarding can be modified to incorporate contour features in a part.
	Two Blade Dies Dies in this series are ideal for very tight joining locations up against a flange where the blades can operate parallel.

Die Holders

Standard Tog-L-Loc die holders are available for a number of Tog-L-Loc dies. Please reference the catalog below for more information.
