SKILSAW Expands Concrete Scoring Offering with MEDUSAW Walk Behind Saw for Concrete

SKILSAW has taken the next step in scoring concrete with the introduction of its 7-Inch MEDUSAW™ Walk Behind Worm Drive Saw for Concrete, model SPT79A-10. This new walk-behind saw satisfies a user’s need for a complete, ergonomic solution for scoring concrete in larger-area applications where productivity is important. This saw incorporates the same wet/dry dust management system and powerful worm drive motor as MEDUSAW, with the addition of an efficient walk-behind configuration.

The MEDUSAW walk behind is equipped with an adjustable arm that extends to the user’s height and folds and locks into place for transporting and storage. A larger handle and two-finger trigger provide greater control when making long cuts. An ambidextrous side assist handle gives added support.

“To avoid lost parts or worn-out attachments, SKILSAW created the MEDUSAW walk behind saw as an all-in-one solution for large cutting applications such as control joints in a commercial build,” said Gregg Mangialardi, Product Manager at SKILSAW. “We’ve seen the way pros have modified their saws, and it inspired us to create this integrated tool to meet their needs as well as Underwriters Laboratories’ [UL] requirements.”

In addition to the walk-behind feature, SKILSAW also designed the MEDUSAW walk behind worm drive saw with an improved pointer for stronger support, and a larger wheel for greater visibility. The three-point line of sight allows for accurate cuts, while a large foot and oversized wheels increase the saw’s stability. The MEDUSAW walk behind saw’s guard and foot are made of die-cast aluminum housing for durability, with zinc-plated brackets and fasteners to protect against corrosion.

Similar to the original MEDUSAW, this walk-behind saw will help users meet OSHA silica exposure limits with integrated dust control in both wet and dry operation. Visit for specific recommendations for managing silica exposure.

The MEDUSAW Walk Behind features the same powerful Dual-Field™ worm drive motor with added overload protection, to protect the motor from the end user inadvertently driving the saw forward too quickly. The saw also accommodates commonly available seven-inch blades.

The MEDUSAW Walk Behind Worm Drive for Concrete, model SPT79A-10, will be available beginning in January at World of Concrete. To learn more, visit
