I have often described our meetings with OEM R&D teams as a lesson in physics. It can also sometimes be like a foreign language lesson. Golf equipment terminology can be as intimidating as a long iron over water. For the gearhead looking to expand their knowledge base or those simply looking to get to know the subject of golf equipment better, we’ve compiled 14 of the most common – and often confusing – equipment terms and tried to narrow them down. explain in their simplest, easiest way. – in order to understand. We won’t have a final exam, but if you read the following carefully, you’ll be fluent in gear in no time.

The degree to which the sole of a club tilts upward and away from the ground plane when the club is in a square setup position. In general, more bounce is better for soft sand and tall, lush grass; less bounce is better for firm sand and turf.

Heel-to-toe face curvature that corrects spin on mis-hits.

The measurement of the radius of the sole from front to back or heel to toe.

How to make a club head by pouring molten metal into a mould.

A theoretical point that defines the average location of weight in a clubhead and the internal point around which an object rotates. A low CG helps launch the ball higher. A club’s CG is not always at its geometric center.

Computer Numerical Control (CNC) milling is a process in which an automated machine cuts and shapes solid blocks of metal by reading a code. Grooves and faces are often made this way to ensure tight tolerances.

The USGA developed it to measure spring effect using a characteristic time (CT) measurement. The allowed limit is 239 microseconds – this is the length of time the clubface remains in contact with a small steel ball swung from a pendulum device at the moment of impact. An 18 microsecond tolerance is also added, so although the limit is 239, any driver measuring 257 microseconds or less passes the test. The test is not limited to the center of the face, but to several points on the face where an impact can occur.

When holding a face-up putter when balanced at the tip of the shaft, a face-balanced putter should be perfectly level. This style of putter is generally believed to work well with relatively straight and straight shots.

A type of clubhead construction where part of the clubface wraps around the crown and sole part, allowing more rebound at impact. Once only found in metal woods, it is now a staple of some irons, many of which use an L-face, where the face only wraps around the sole, not the topline, because most iron impacts are low on the face.

A method of making a clubhead by heating metal and then stamping it into shape.

Although often thought of only as a measure of a club’s resistance to twisting on off-center hits, the moment of inertia is really a method of mitigating the loss of ball speed on mis-hits. The USGA limit for conductors is 5900 grams/square centimeters.

A lightweight, durable synthetic material that can be engineered to meet a range of hardnesses. The material is often used inside iron club heads to improve feel.

Often refers to wedges where an area of ​​material on the sole has been removed to increase versatility and reduce turf drag.

The angle of the putter’s tip deviates from horizontal when balanced at the tip of the shaft. In general, the higher the angle, the better it is for arcing putts.
