Frequently Asked Questions

Q: What type of electric hammer is this expansion bolt strike punch compatible with?

A: This strike punch is designed for use with both light and heavy electric hammers. It is available in round and square SDS shank types, making it compatible with a wide range of electric hammer models commonly used in construction and DIY applications.

Q: How does the concave head protect the expansion bolt thread?

A: The concave head design centres directly over the bolt head, distributing the impact force evenly and preventing the punch from sliding off. This focused contact means the thread itself is never struck, eliminating the risk of thread stripping or deformation during installation.

Q: What material is the strike punch made from, and why does it matter?

A: The punch is machined from 40CR alloy steel, a high-strength chromium alloy steel known for its excellent hardness, toughness, and wear resistance. This ensures the tool can withstand repeated heavy hammer impacts without deforming, giving you long-lasting, accurate performance on site.
