Mayhew 5/16" Point Size Center Punch (41702)
The Mayhew 5/16" Point Size Center Punch (41702) is a professional-grade hand tool engineered for creating precise indentations on workpieces, primarily metal, before drilling. This crucial step prevents drill bits from "walking" or deviating from the intended spot, ensuring accurate and clean holes. Crafted from high-grade, heat-treated alloy steel, this center punch offers excellent durability and performance for various marking applications. Its black oxide finish provides enhanced protection against rust and corrosion, extending the tool's lifespan. Proudly made in the USA, the Mayhew 41702 Center Punch is a reliable addition to any toolkit, whether for professional tradespeople or dedicated DIY enthusiasts who prioritize precision and efficiency in their projects.
KEY FEATURES AND BENEFITS:
Accurate Hole Starting: The precisely ground 5/16" point creates a clear, defined dimple, guiding drill bits to their exact starting location and eliminating drill wander for improved accuracy.
Reduced Drill Bit Slippage: By providing a pre-marked indentation, the punch minimizes the risk of drill bits skidding across the material surface, leading to safer and more controlled drilling.
Versatile Material Application: Effective for piercing and marking on a wide range of materials, including various metals and other surfaces, preparing them for subsequent drilling or other processes.
Robust Construction: Manufactured from high-grade, heat-treated alloy steel, ensuring exceptional strength and resistance to wear for a long service life.
Corrosion Resistance: Features a black oxide finish that offers superior protection against rust and corrosion, maintaining the tool's integrity over time.
Optimal Grip and Stability: The 1/2" hex body design provides a secure and comfortable grip, preventing the tool from rolling on flat surfaces and enhancing control during use.
American Made Quality: Produced in the USA, reflecting a commitment to high manufacturing standards and reliable performance.

Included in Product: One (1) Mayhew 5/16" Point Size Center Punch (41702) in carded packaging.
Prepare the Workpiece: Place your material, such as metal, on a stable and secure surface. Ensure it is firmly clamped or held to prevent movement during the marking process.
Identify Marking Point: Clearly determine the precise location where you intend to drill or create an indentation. You may use a pencil or marker for an initial visual guide.
Position the Center Punch: Place the pointed end of the Mayhew 5/16" Center Punch directly onto your marked location. Hold the punch firmly and perpendicular to the material surface.
Strike with a Hammer: With a hammer (a ball-peen hammer is commonly used), deliver a single, firm strike to the flat, top end of the center punch. The force of the strike should be sufficient to create a visible, small indentation in the material.
Verify Indentation: Lift the center punch and inspect the created dimple. It should be clear, conical, and precisely where you intended the drill bit to start. If necessary, you can repeat the process with a lighter tap to deepen the mark.
Proceed with Drilling: Once the indentation is satisfactory, you can confidently proceed with your drilling operation, knowing the drill bit will start accurately within the marked dimple.
