Pitching wedges have a loft of between 46 and 48 degrees. Approach wedges have lofts between 50 and 52 degrees. The extra loft on the approach wedge helps it to get up in the air, but decreases the distance hit.
A pitching wedge is the lowest-lofted of the named wedges, used to hit a variety of short-range shots. The modern pitching wedge has a loft of around 48Â° (exact lofts vary by clubmaker and player preference) and little or no bounce (angle of the sole to the ground).The pitching wedge is descended from the niblick, an obsolete blade-style club with a high loft.he modern sand wedge still uses the ideas of high mass, high loft, and bounce angle, but the modern sand wedge clubhead has much higher mass than earlier designs, up to 40oz (2.5 lb, 1.13 kg), to drive the clubhead through the firmer sand found in many courses.
