The improved bowling ball tool kit includes a tool having an elongated shaft with an expanded handle on one end and one of a number of bowling ball finger hole scrapers of differing diameters supplied by the kit. The scrapers are separately releasably attachable to the opposite end of the shaft of the tool. The scrapers are preferably formed of silicon carbide or another hard material which will readily ream, slice or abrade the plastic of a bowling ball to enlarge its finger holes. The kit also includes a connector, preferably in the form of a threaded connector bolt to releasably hold the scrapers in place by threading into the shaft end after passing through a central hole in the scraper. Each of the scrapers is frusto-conical disc and is mountable on the shaft end so that the sides of the disc taper down and away from the shaft. The tool and kit are simple, durable, small, portable, inexpensive and efficient to enlarge bowling ball finger holes so as to accommodate fingers with gradually increase in diameter as bowling is practiced.
