NEIKO 02604A Hole Punch Set – 14-Piece, SAE & Metric (3/16 in – 1-3/8 in, 5–35 mm) with Center Punch

Overview

The NEIKO 02604A Hole Punch Set is a versatile, precision-oriented toolkit designed for clean, accurate cuts across a range of materials. The kit covers both SAE and metric sizes from 3/16 in up to 1-3/8 in (roughly 5 mm to 35 mm), giving you a broad workspace without swapping tools. Crafted from hardened carbon steel, the hollow punches hold their edge through repeated use, while a six-inch handle provides steady leverage. The knurled grip promotes confident control, whether you’re creating gaskets, leather holes, or simple reference marks.

Build and durability

Each hollow punch is heat-treated for durability, offering consistent performance across multiple punches in a single session. The included center punch helps you start holes with precision, reducing slippage on delicate or flexible materials. The entire set is designed to be used with a flat, stable surface, which contributes to cleaner, more repeatable results over time.

Versatility at a glance

• Gasket and washer creation across leather, rubber, vinyl, foam, carpet, cardboard, and soft metals.
• Center-punch integrated for accurate positioning, removable for full circle cuts.
• Knurled, screw-in punch heads for safe, secure use with the six-inch handle.

What’s included and how it’s organized

• Thirteen hollow punches spanning 3/16 in to 1-3/8 in (5 mm to 35 mm) in both SAE and metric sizing.
• One six-inch steel handle with a knurled interface for a secure grip and easy handling.
• Carrying case to keep all components protected and neatly organized between uses.

How to use

1. Mark the hole center on a flat, clean surface for best results.
2. Attach the appropriate punch to the handle and tighten securely.
3. Use the spring-loaded center punch to align the mark; for pure circle cuts remove the center pin if needed.
4. Position the tool vertically over the workpiece and strike the top with a hammer.
5. Apply controlled force; excessive hammering can damage the tool or material.

Tips for best results

• Use on a flat, even surface and place a wooden or plastic underlay to protect the workpiece and punch.
• Carefully manage the center pin: removing it enables full circle cuts and can prevent disc damage.
• Mark centers clearly and punch with a steady, vertical motion for consistent outcomes.

Real-life use ideas

In a craft or workshop setting, this kit helps customize leather straps, belts, or bags with precise hole spacing. It also supports gasket work in small assemblies, foam prototyping, and soft-material projects where clean, defined holes matter. The 26 size range offers quick adaptability without hunting for multiple tools during a project.
