Form A, <strong>with</strong> annular bead<br />
Special purpose drill for producing center<br />
holes to <strong>DIN</strong> 332, sheet 1, form A (<strong>with</strong>out<br />
protecting chamfer),except for an annular<br />
groove at the junction of the countersink<br />
and the drilled hole.<br />
Special features of these tools are: highfeature<br />
resistant properties, specially<br />
strengthened form at the junction of the<br />
pilot and body which permits high metal<br />
removal rates, special form cuts annular<br />
groove which acts as a reservoir for the<br />
lubricant.<br />

R<br />
Standard drill for producing center holes<br />
to <strong>DIN</strong> 332, sheet 1, form A (<strong>with</strong>out protecting<br />
chamfer).<br />
High heat resistant centering drill.<br />
Especially suitable for high thermal load<br />
applications. For drilling materials <strong>with</strong> a<br />
tensile strength of over 800 N/mm 2 as<br />
well as stainless steels, acid and heat<br />
resisting CrNi-steels.<br />

Form R<br />
R<br />
Special purpose drill for producing center<br />
holes to <strong>DIN</strong> 332, sheet 1, form R<br />
(radiused)<br />
Advantages of these tools are:<br />
1. precise concentricity of the point in<br />
relation to the body.<br />
2. radiused form providing a protected<br />
center hole.<br />
Point grinding: relieved cone<br />
Point angle: 118˚<br />
