Reaction Characteristics
The Hammer Tour Offset is in response to feed back from many bowlers who bowl on competitive/challenging conditions. When a low R.G. high flare ball tends to burn off energy quickly and not have the back end motion to carry the pins, the Tour Offset is the ball to go to. With a higher R.G. and lower flare potential, the Tour Offset reacts to friction further down the lane as compared to previous Offsets and offers a more defined break point with more continuous back end hook. What this inspires in the bowler, is more confidence in the back end reaction, and a higher entry angle for improved pin carry.

Quick reference drilling suggestions
All layouts are for right handed bowlers. For left handed bowlers simply reverse procedures (mirror image)
HIGHER TRACK PLAYERS (ball track within 1 1/2" of thumb hole) and also STROKERS
- Select ball with pin 1" - 3" out.
- Position pin approximately 1" right of ring finger.
- Position HOT SPOT approximately 1 1/2" right
of center line, as shown. - If balance hole is required, mark line from center
of grip through C.G. and drill balance hole 5 1/2".
from center of grip on that line. Balance hole may
be drilled above or below midline.
MEDIUM HOOK (HIGHER TRACK PLAYERS AND STROKERS)
Select ball with pin 2" - 4" out.
- Position pin above finger holes on center line, as shown.
- Position HOT SPOT approximately 1 1/2" right of
center line, as shown. - If balance hole is required, mark line from center of
grip through C.G. and drill balance hole 5 1/2" from
center of grip on that line. Balance hole may be drilled
above or below midline.
LOWER TRACK PLAYERS (ball more than 1 1/2" from thumb hole) and also CRANKERS
-
Select ball with pin 2" - 4" out and less than 3.0 oz top weight. Position pin 45 deg. , just above ring finger, as shown. Position HOT SPOT approximately 3" right of center line, as shown. If balance hole is required, mark line from center of grip throughC.G. and drill balance hole 4 1/2" from center of grip on that line.
Balance hole may be drilled above or below midline.
MEDIUM HOOK (LOWER TRACK PLAYERS AND CRANKERS)
![]() |
Select ball with pin 2"- 4" out and less than 3.0 oz top weight. |
Position pin 1 1/2" right of ring finger, as shown.
Position HOT SPOT approximately 4" right of center line, as shown. Drill balance hole at C.G. Balance hole may be drilled above or below midline. |
Break points for suggested drillngs can be easily adjusted with
surface changes. A higher lustre of polish will result in more
length and a later break point while maintaining the back end
reaction, a duller surface or sanding the ball will result in an
earlier breakpoint with the desired back end reaction.

Precision Drilling suggestions
THE P.A.P. IN THE DRILLING SUGGESTIONS IS THE BOWLERS POSITIVE AXIS POINT
The suggested layouts are for right handed drillling. Reverse the drilling procedure (mirror image) for left handed drilling.
The Center Of Gravity (C.G.) is identified by an engraved 1/4" circle. The suggested drilling illustrations show the C.G. located on a visual line from the Top Pin to the Hot Spot (locator Pin) and is strictly for reference. With the core body offset, C.G. can fall left, right or be centered on the visual line from Top Pin to the Hot Spot. When balance hole is required, mark line from Center of Grip through C.G. and drill balance hole on that line at the intersection of the vertical axis line. Balance hole may be drilled above or below the mid line.
---------------3 3/8" STRONG-----------------
-
DESIRED REACTION: Large flare, maximum hook, strong back end. LANE CONDITION: Medium to heavy oil blend.
PIN PLACEMENT: 3 3/8" from P.A.P.
(use ball with pin 1" - 4" out)
HOT SPOT PLACEMENT: 2" left of vertical axis line.
This drilling will produce the sharpest break point obtainable
in the 3-D Offset Hammer. Use this layout when trying to
open up the lane and create area on a blended lane condition.
Too reactive for wet/dry conditions.
-----------3 3/8" CONTROLLED------------
- DESIRED REACTION: Large flare, large hook, controlled back end.
- LANE CONDITION: Medium to heavy oil with carry down.
- PIN PLACEMENT: 3 3/8" from P.A.P.
(Use ball with pin 1" - 4" out and less than 3 oz. top weight) - HOT SPOT PLACEMENT: Position Hot Spot on the vertical axis line.
This drilling will result in a more controlled back end by
generating heavy forward roll from the break point to the pins.
Great for low track players.
------------------3 3/8" ARC------------------
- DESIRED REACTION: Large flare, medium hook, smooth arc.
- LANE CONDITION: Medium to heavy oil with a hooking ball track.
- PIN PLACEMENT: 3 3/8" from P.A.P.
(use ball with pin 1" - 4" out) - HOT SPOT PLACEMENT: 4 1/2" left of vertical axis line
Hot Spot will be left of the center line.
This drilling produces a smooth arc with a large flare pattern.
Not recommended for an inside line.
------------------5" STRONG------------------
- DESIRED REACTION: Medium flare, medium hook, strong back end.
- LANE CONDITION: Medium oil with dry back end.
- PIN PLACEMENT: 4 1/2" - 5 1/2" from P.A.P. (use ball with pin 2" - 4 1/2" out)
- HOT SPOT PLACEMENT: 3" left of vertical axis line.
This drilling will produce Medium hook with a late break point.
Good for playing inside the ball track.
--------------5" CONTROLLED---------------
- DESIRED REACTION: Medium flare, medium hook.
- LANE CONDITION: Medium oil with carry down.
- PIN PLACEMENT: 4 1/2" - 5 1/2" from P.A.P.
(use ball with pin 2" - 4 1/2" out and less
than 3 ounces top weight) - HOT SPOT PLACEMENT: Position Hot Spot on the
vertical axis line.
This drilling will produce medium hook, with
controlled back end by generating heavy forward
roll from the break point to the pins. Good for
wet/dry conditions.
---------------------5" ARC---------------------
- DESIRED REACTION: Medium flare, smooth arc.
- LANE CONDITION: Medium to light oil with a
hooking ball track. - PIN PLACEMENT: 4 1/2" - 5 1/2" from P.A.P.
(use ball with pin 2" - 4 1/2" out) - HOT SPOT PLACEMENT: 4 1/2" left of vertical
axis line. Hot Spot will be left of the center
line.
This drilling will produce an even arc reaction.
Not recommended when playing a deep inside line.
------------------2" STRONG-------------------
- DESIRED REACTION: Early revolutions, strong
back end reaction. - LANE CONDITION: Medium to light oil.
- PIN PLACEMENT: 1 1/2" - 2 1/2" from P.A.P.
(use ball with pin 1" - 3" out and less than 3 oz. top
weight) - HOT SPOT PLACEMENT: 1 1/2" left of vertical axis
line.
This drilling will produce early revs in the front part of the lane
with medium flare and a strong reaction at the breakpoint.
----------------------2"ARC--------------------
- DESIRED REACTION: Early revolutions with controlled
back end. - LANE CONDITION: Medium to light oil with strong
reacting back end. - PIN PLACEMENT: 1 1/2" - 2 1/2" from P.A.P.
(use ball with pin 1" - 3" and less than 3 oz. top weight) - HOT SPOT PLACEMENT: Position Hot Spot on the
vertical axis line.
This drilling will produce early revs in the front part of the lane
with controlled reaction at the break point by generating strong
forward roll from the break point to the pins. Great for wet/dry
conditions.
--------------2" CONTROLLED--------------
- DESIRED REACTION: Early revolutuions with
a smooth arc. - LANE CONDITION: Medium to light oil with a hooking
ball track. - PIN PLACEMENT: 1 1/2" - 2 1/2" from P.A.P.
(use ball with pin 1" - 3" out) - HOT SPOT PLACEMENT: 4 1/2" left of vertical axis

This drilling will produce early revs in the front part of the lane
with smooth arc. Good for playing a direct trajectory when the
ball track is hooking.

LOVE THIS BALL HITS REAL HARD AND CLEARS THE DECK WHEN YOUR AROUND THE HOLE. ONLY REAL PROBLEM AS I SEE IT IS IF YOU PULL THE BALL IT WILL JUST HANG IN THE MIDDLE. BUT AS LONG AS YOU CAN GET IT OUT IT WILL COME BACK TO THE HOLE. GREAT BALL FOR WET LANES HAS VERY GOOD CARRY TO IT. FIRST TIME USING IT SHOT 208, 217, 222 AND 279 WITH NOT BAD FOR THE FIRST TIME THROWIN A BALL. STARTS HOOKING AROUND MID LANE AND DRIVES THROUGH THE CARRY CARRY DOWN. ALL AROUND GREAT BALL FOR ANY TYPE OF LANE
