EMHD headed economy button die: historical specification

A bounded example from the 2010 India press catalogue.

Reference configuration

The historical source gives the ordering example EMHD 13–30–P7.00. It is a reference for reading the catalogue, not a quotation or a confirmed current SKU.

Field	Source value / interpretation
Series	EMHD, headed economy type
Material / hardness	SKD11 equivalent, 60–63 HRC
Nominal D	13 mm; m5 offsets +0.007 / +0.015 mm
Nominal L / P in the example	30 mm / 7.00 mm
Evidence location	PDF page 1, printed spread 259–260

Interpretation: the stated shank limits are 13.007–13.015 mm. Do not transfer this row to another diameter, tolerance option or series.

Drawing notation: D = shank diameter; L = overall length; P = round-hole diameter; b = cutting-land depth; d = relief diameter; H = head diameter; T = head thickness. Unaltered drawing tolerances: P +0.01/0, L +0.4/+0.2, H 0/−0.2, T +0.3/0 mm. Refer to the original for geometric controls, lead geometry and alteration conditions.

SHAPED HOLES · PRESS 2010

Check D / R / E / G hole dimensions

These 16 series share the source material and shank-tolerance families. Shape letters follow the original drawing. This dimensional check excludes alterations and is a request for engineering review, not an approved manufacturing drawing.

SeriesShank D (mm)Length L (mm)P (mm)W (mm)Corner R (mm; R type only)

How the dimensions are checked

D: P ≥ W; K = √(P² + W²), within the row maximum.
R: P ≥ W; 0.15 ≤ R < W/2; K = √((P − 2R)² + (W − 2R)²) + 2R, within the row maximum.
E and G: P > W; P within the row maximum.
P and W meet the row minimum. P, W and selectable R use 0.01 mm increments; shaped P/W tolerance is ±0.01 mm.

D and G drawings specify corner R ≤ 0.2 mm. The R-type radius input is a different parameter. Shape, orientation, geometric tolerances, lead and holder fit still require comparison against the original drawing.

Selected alteration conditions for drawing review

The following conditions are not applied by the selector. Ask for an altered drawing separately; satisfying an individual rule does not approve a combination. PC/WC, key-flat orientation, paired finishing and retainer-surface details remain in the original document for review.

Code	Historical condition
LC	10 ≤ L − (b − 1) ≤ LC < L; 0.1 mm steps. With LKC, LKZ, CKC or MKC: 0.01 mm steps. Cutting depth b and lead decrease by L − LC.
LKC	Length tolerance becomes +0.05/0 mm.
LKZ	Length tolerance becomes +0.01/0 mm; L or LC must be at least 16 mm and D must not exceed 25 mm.
HC	D ≤ HC < H; 0.1 mm steps.
TC	2 ≤ TC ≤ 5 mm; 0.1 mm steps (0.01 with TKC, TKM, CKC or MKC). Length decreases by 5 − TC. Combined with LC, final length equals LC.
TKC / TKM	Head-thickness tolerance: +0.02/0 or 0/−0.02 mm respectively. L or LC must be at least 16 mm.
SKC	Shank key flat: D ≥ 8 and L or LC ≥ 20 mm; cannot combine with KC, WKC or KFC.
