Q Max Sheet Metal Hole Punch Metric
The Q Max 21mm Sheet Metal Hole Punch provides robust cutting capability for larger apertures in sheet metal up to 16 gauge. This size is particularly useful for sizeable conduit installations, larger cable glands, and applications requiring a 21mm hole diameter.
Engineered with heat-treated cutting edges and a black anti-corrosive finish, this punch delivers clean, burr-free holes consistently. The special design distributes cutting load evenly, ensuring smooth operation and reducing operator fatigue during extended or repetitive use.
This larger punch utilizes the modified configuration with the thread located in the punch body itself, eliminating the need for a die nut. This streamlined design simplifies assembly and speeds up operation. An 8mm hexagonal wrench (MB type) is required to turn the mechanism and pull the punch cleanly through the metal.
Features and Benefits:
• 21mm diameter ideal for larger conduit and mounting applications
• Requires 8mm hexagonal wrench (MB type, sold separately)
• Simplified larger-size configuration for efficient operation
• Heat-treated cutting edges ensure durability
• Burr-free holes save time and effort
