Punches, retainers, and punch blanks are available in sizes other than those listed in the configurator.   These special order products can be manufactured for a slight additional charge.

When configuring, you are asked to specify different designations for various non-standard dimensions.  Once you have set the base information you can choose from the list of available alterations.  Below is for reference.

Length Alterations

XBR (Straight Before Radius) It is recommended that point lengths be kept as short as possible for optimum strength

	XL	Overall Length Shortened (1.00 min.) Stock removal from point end which shortens L1 length
	XLB	Overall Length Shortened Stock removal from point end. Point length L1 maintained (Min. shank length .75)
	LL	Precision Overall Length Same as XL except overall length is held to ±.001
	XK	No Side Hole For air ejection. No cost
	XS	Shear Angles See information below
	XJ	Smaller Jektole Components

Shear Angles (XS)

TuffPunch^® products are available in common shear angle configurations for all standard shapes.

Shear angles are available in any angle.  Specify angle in whole degrees. if half degree is necessary, specify as a decimal, e.g., 8.5° (tolerance on all angles is +-15 minutes.)  Use the chart below to determine the product designation, then simply add the alteration code shown next to the drawings, along with the angle desired.

LL not available on XS19, XS21, XS22 and XS23.

Our TuffPunch^®  line of punches are available with the most common locking devices, flat, double flat and dowel.  The standard location is at 0°, alternate locations of  90°, 180°, or 270° are available at no additional charge.

If you require a custom location we offer that as well use the Custom Locations codes below and specify your angle.  All custom locations are measured counterclockwise from 0°.

Single Flats

For Standard and Alternate Locations, specify X2

For Custom Locations, specify X5

Double Flats

For Standard and Alternate Locations, specify X3

For Custom Locations, specify X6

Second Flat is Always Parallel to the first flat.

Additional Flats

Dowel Slots

For standard and Alternate Locations,
specify X4 (.125 Dowel)  or X41 (.1875 Dowel)

Coatings & Treatments

Punches can be coated to increase material hardness, reduce galling, and improve wear/ and or corrosion resistance.

Surface Treatments

DayTride® (XN) - A low temperature, cost- effective surface application that treats all exposed surfaces. Provides increased dimensional stability. Ideal for punches and die but- tons. Approx. hardness: RC65-73.

XVP - A thin film coating provides superior hardness (harder than carbide). Super-smooth finish on the point helps reduce galling and maintenance. Ideal for higher-than-normal punching frequency.

XPS - Super-smooth polish on the point to reduce galling and improve punch life. Use with the appropriate coating for your application to maximize punch life and reduce maintenance costs. Excellent for extruding applications.

Abrasive Wear

DayTiN® (XNT) - Excellent wear resistance and lubricity. Not recommended for stainless steel, copper, or nickel. A good general- purpose coating. Approx. hardness: *Vickers 2300.

TiCN (XCN) - Ultra-hard (harder than carbide), thin coating. Provides superior abrasive wear resistance and lubricity. A very good general- purpose coating for all materials. Upgrade over XNT. Approx. hardness: *Vickers 3000.

DayTAN™ (XAN) - Ultra-hard (harder than carbide), high-aluminum coating. Provides high temperature resistance. Well-suited for applications where surface heat is generated. Ideal for HSLA, dual phase, and TRIP steels. Upgrade over XCN. Approx. hardness: *Vickers 3400.

ZertonPlus™ (XNA) - Superior hardness (harder than carbide); provides superior abrasive wear resistance and excellent lubricity. Provides highest temperature resistance, thermal shock stability, & hot hardness. Approx. hardness: *Vickers 3200.

Adhesive Wear

XNM - A solid lubricant coating. Provides both lubricity and wear resistance not available from other PVD or CVD processes. Ideal for aluminum, copper, pre-painted, and galvanized steels. Approx. hardness: *Vickers 2000.

XCD - Diamond-like carbon coating. Combines high hardness with an extremely low coefficient of friction. Good protection against abrasive and adhesive wear. Ideal for aluminum. Approx. hardness: *Vickers 5000.

XCDH - Super-smooth finish combined with advanced DLC coating for a very low coefficient of friction with extremely high wear resistance. Approx. hardness: *Vickers 5000.

XCDP - Super-smooth finish combined with a DLC coating for a very low coefficient of friction with high wear resistance. Excellent for stamping aluminum. Approx. Hardness: Vickers 2800.

Extrusion Coatings

XNP - The ultimate coating for improved resistance to galling; excellent wear resistance, superior surface finish, and high lubricity. Ideal for extruding and forming applications. Tolerance is ±.0002”. Approx. hardness: *Vickers 3100.

XNAProgress (XNAP) - Ultra-hard coating that absorbs shear stress; provides excellent high-temperature resistance. Ideal for stamping where tools are exposed to extreme stress pro- files. A good alternative to TD coating without the dimensional changes associated with that process. Approx. hardness: *Vickers 3200.

Miscellaneous Coating

CRN - Excellent adhesion, high toughness, and good corrosion resistance. Primary applications are metal forming (copper, brass, & bronze), metal die casting, and plastic injection molding. Approx. hardness: *Vickers 1800-2100.
