Infamous performance!

The technology-packed core and strong solid cover produce a motion that is extremely useful and unique. Bowlers looking for a big symmetric ball shape will have to have this in their bag.


The Infamous core is a new design, and while it’s symmetric, it is packed with technology. Hammer is back to using multi-densities within the core to create new ball motions. The Infamous core has a large extra-dense flip block that sits on the top of the core body, and it features a radial disc on the bottom of the ball that helped give the original Obsession extra motion on the backend. There are four densities on the inside of the Infamous, including the famous Carbon Fiber outer core. Featuring DOT technology, which allows you to drill anywhere which makes this ball even tougher.

    Interesting core/cover combination

    Had no idea what this was going to do when hammer announced it, but I'm glad I got a couple to drill up.

    The first one I drilled 55 x 4 3/4 x 30, typical drill pattern on new stuff, and it was very controllable, smooth and predictable. Could never really get it to achieve the motion I thought I was going to get, but it ended up being a benchmark ball In one of my league houses that allowed me to get a read on how the lanes were playing that night.

    Fast forward to ball # 2, ended up going with a longer drill pattern, 75 x 5 x 30, and kept surface on it. It read the mids and finished strong, finally the motion I saw a lot of other people getting in their reviews. Im glad I got a second to drill differently, as a small switch to longer angles and surface really helped me get comfortable with this ball and use it more and more each league night. As they have said before, definitely a sleeper type ball!

    Sleepy good ball!

    With the higher RG I decided to try a 60x 5 x 35 drilling. When I first went to test this ball, no kidding it hooked!!, I mean t hooked!!! When it got a little lane shine this ball mellowed out to be one of my all time favorite Hammer bowling balls. With the higher RG it clears the fronts with ease, then the core takes over and it continues off the back. Do not overlook this gem!

    The Hammer Infamous provides a hard arcing reaction on medium to heavy lanes. This reaction is suitable for those bowlers looking for a benchmark type roll. This ball provides good length with end over end movement. I see this ball blending out wet/dry due the cover setup of 500,1000,2000 finish. This one provides optimal hitting power while saving energy at the right spot.

    Infamously Overlooked...

    Many people will sleep on this ball, but I'm glad I didn't. This ball got me my first 300 game. I have had 299 twice, but this ball gave me my first and an 845 series. I shot a 760 with this ball roughly a week later after the 845 series. For me being a lower rev male player (200-250 rpm), this ball has done wonders for me. I drilled it with the pin slightly right of my ring finger and the cg indicator in the center of my hand. The core-coverstock combo is amazing. The cover is fairly strong, which is great for lower rev players by helping the ball to read, but the core with it being higher RG and a good differential helps it get length and keep its backend motion without burning up too soon. This allows a smooth reaction with great hitting power and continuation, with no over-under reaction. I recently resurfaced the ball at 360/2000 and it responded great to the surface adjustment and helped me shoot that 760 series a week later. This tells me it responds great to surface adjustments and is versatile. Was able to play multiple angles with this ball with great continuation.

    For a comparison ball I have the Storm Hy-Road drilled similarly, and for me it worked off that ball very well. For me, the Infamous was earlier and 2 more boards in strength for me, while the Hy-Road was a little cleaner and a great transition piece after 2-3 games.

    Hammer, do a Storm bowling by keeping this ball in production for years to come! Thank you for such an amazing product!

    Just Amazing!

    Not what else to say about this ball. It’s the best ball in my bags right now. It’s darn near tempting to buy a second, just incase something happens to this one.
