Confused with all the golf terminology? Look no further, just check out the list below. If you don't see what you are looking for, just send us an e-mail and we will reply with the definition and explanation..
Bend Point The
point of maximum bending on a shaft measured by compressing both ends inward.
Bounce Sole The sole angle of an iron when the trailing edge is lower than the leading edge when the club face is placed in a square position to the target.
Bulge The horizontal measurement from heel to toe
CPM Cycles Per Minute. A unit of measure for shaft frequency. The number of shaft oscillations that can be counted during a 60-second interval. Measured by a Frequency Analyzer.
Cavity Back Iron An investment cast iron head that has extra weight in the heel, toe and / or sole areas & less weight concentrated directly behind the club face. The most popular iron in golf today.
Center of Gravity A point on the club head where the weight is evenly distributed in all directions.
Core The inside diameter of the grip. Core diameters generally can be found in the following sizes : 0.560 (ladies), 0.580, 0600, and 0.620. On most grips, the core size may be found inside the mouth of the core. (i.e. M60 = Mens 0.600)
Deep Face Wood heads that have a face height of 1 7/8 or higher. Any wood head with a face height higher than standard.
Ferrule A tapered plastic sleeve which forms a smooth transition from the top of the hosel to the shaft.
Flex The designation assigned to a shaft based on stiffness, or ability to resist bending. Designations include ladies (L), amateur or senior (A), regular (R), stiff (S), and extra stiff (X). Please note that the flex indicated on shafts will differ from one manufacture to another.
Forging Another method of club head production where a block of metal is literally pounded into the finished club shape. Because of the physical nature of this type of production, it does not allow for intricate design features.
Frequency The number of oscillations of a shaft over a know period of time after the tip is pulled down & released while mounted in a frequency-measuring device. Measured in cycles per minute (CPM)
Frequency Matching The method of measuring and adjusting a clubs CPM in relation from one club to another. Usually 4-7 CPM between clubs. This method assures that the clubs will all load & release at a certain point during the swing. Please note that 2 identical & uncut steel shaft may differ approximately by 5 CPMS (approximately ½ flex) while graphite shafts may differ by as much as 10 CPMs. (approximately 1 full flex)
Heel The lower portion of the iron head closest to the hosel & shaft.
Hosel (a.k.a. Neck) The portion of the club head that protrudes vertically from the heel and secures the shaft.
Investment Casting The predominant method of golf head manufacturing today. Investment casting involves the introduction of molten metal (usually stainless steel) into ceramics shells or molds. This method allows for very intricate designs to be made on a consistent basis with supreme perimeter weight qualities.
Kick Point the point of maximum bending on a shaft measured by deflecting the tip end of the shaft with the butt secured.
LCG (Low Center of Gravity) A club head with more weight placed towards the sole of the clubs to help get the ball more airborne.
Leading Edge The forward most part of the sole closest to the target.
Lie Angle The angle between the shaft centerline & the sole of a golf club in its playing position. Measured in degrees.
Loft Angle The angle created by measuring the line down the center of the club face in relation to the center of the hosel bore.
Moment of Inertia (MOI) A club heads ability to resist twisting on off-center contact. Perimeter weighted clubs are described as having a higher moment of inertia.
Muscle Back Iron An iron (usually forged) that features a smooth backside and limited perimeter weighting.
Offset The physical positioning of the hosel, shaft & grip ahead of the club face. Offset allows the player to get his hands through the ball thereby helping him hit it straighter.
Roll The vertical measurement of face radius from top to sole.
Seamless Shaft A steel shaft produced from a non-welded, seamless drawn steel tube.
Shallow Face Wood heads that have a face height of 1 3/8 or less. Any wood head with a face height lower than standard.
Sole Radius (a.k.a. Camber or Rocker Sole) The curved portion of the bottom of the club that helps it glide smoothly through the swing without digging into the ground or catching in the grass. Found in both woods & irons.
Spining The method of locating the longitudinal spine (weak point) of any given shaft & orienting it in a neutral position. Please note that graphite shafts have 2 spines while steel shafts have only 1.
Sweet Spot Literally the center of gravity of a golf club. On the face of a golf club, this are will be represented by a single microscopic point. As such, it is impossible for any club to have a bigger (or smaller) sweet spot than any other club. It is, however, possible to have a larger hitting area.
Swingweight A measurement showing the weight distribution of a golf club about a fixed fulcrum position (typically on a 14 fulcrum swingweight scale). An expression of the relationship between the grip & head of a golf club written as a letter / number designation (D-2, D-3, etc.)
Toe The upper area of an iron head farthest from the hosel.
Torque the twisting of the shaft that occurs as the club head is swung & impacts the ball. Evaluated by clamping the butt end of the shaft & applying an angular force on the tip end. Measured in degrees.
Total Weight the overall weight of an assembled golf club as measured in ounce or grams.
