If you do any kind of woodworking, assembly projects, or delicate hammering, these rubber hammer tips are seriously useful. You get two sets - one yellow and one black - with 35mm diameter heads that fit standard hammers with M10x1 threading. The soft rubber is perfect for when you need to tap things into place without marring surfaces or causing damage. They're great for assembling furniture, installing trim, working with automotive parts, or any situation where metal hammers would leave marks. The rubber is durable enough to handle repeated use but soft enough to protect your work. The threaded design makes swapping between different hammer heads quick and easy. Much better than trying to use a regular hammer with a cloth or something between it and your workpiece. The quality feels solid - they're not going to split or deform with normal use. If you've ever damaged something because your hammer was too hard, these rubber tips will save you so much frustration and ruined projects.
