SPS/SPi Series Hammers

Find Nupla SPS and SPI series hammers at The Hammer Source.

What's the difference?

SPS hammers are cased in a super tough polymer jacket and molded to a fiberglass handle while inside the SPI hammer is a composite encased, shot-loaded deadblow hammer. Both are molded onto a Nupla fiberglass handle. Each hammer comes in the 1", 1 1/2", 2", 2 1/2", and 3" diameters with various head weights and handle lengths. Faces are either cylindrical, wedge or dome shaped. Most face sizes come in 8 durometric hardnesses from Super Soft to Extra Hard. These hammers come with out faces so you can select the ones you need for your task.

Nupla SPS Hammer and SPI Hammers look like this (1" to 3"):
