The Automatic Center Hole Punch is a High Quality Hand Tool and engineered to meet the requirements of Drilling Machining. Its primary function is to produce a Consistent, Centralized Mark in a variety of Materials. The punch is made out of Chrome-Vanadium Steel and will not require the use of a Hammer. The punch utilizes an advanced Internal Spring Loaded Mechanism that creates Kinetic Energy when the User applies Downward Pressure. When the User reaches a specific Threshold, the Spring releases a High-Impact Strike through the Hardened Tip of the Punch, creating a Deep Indentation in the Work Piece. This controlled release of Energy guarantees that the resulting Mark created by the Punch will be sufficient to Guide a Drill Bit, and thus eliminates the problem of "Bit Walk", which occurs when a Drill Slides Across a Smooth Surface and Damages the Finish of the Material.
The Versatility of the Punch is based upon its Adjustable Impact Feature. Typically, this is accomplished through a Knurled Cap located at the Top of the Handle. The User may rotate this Cap to either Compress or Loosen the Internal Spring within the Punch, therefore Increasing or Decreasing the Force of the Strike. Therefore, this adjustment is critical when switching between various Surfaces. For example, when punching Softwoods or Thin Plastics, a Lighter Setting is usually used so as to avoid Cracking or Over Penetration. On the other hand, when punching Hardened Chrome-Vanadium Steel, Iron, or Thick Aluminum, the User can Dial-up the Tension so that the Punch Leaves a Clear Visual Mark in the Dense Metal. The Body of the Punch is Ergonomically Designed with Textured Grip to provide Friction to prevent slippage, regardless of whether or not the User is wearing Gloves while working in their Shop Environment.
In Metal Working, the Automatic Center Punch is essential for providing Layout Accuracy. Prior to the time that a Drill Bit comes into contact with a Metal Plate, the Punch provides Physical Contact for the Point of the Drill Bit to allow for Holes to be drilled Exactly Where Design Specifications dictate. This is particularly Important when working with Chrome-Vanadium Steel, since this type of Steel is Extremely Hard and Resistant to Abrasion. A Standard Drill Bit would have difficulty finding a Seat on a Flat Surface of Chrome-Vanadium Steel; however, the Hardened Tip of the Punch, which is Heat-Treated to a Higher Rockwell Hardness Value than the Material being struck, Easily Compromises this Resistance. Thusly, Expensive Errors are Prevented and Time is Saved because Repeated Measuring and Re-Drilling become Unnecessary.
Outside of Industrial Metal Work, this Punch is also useful in Wood Work and Plastic Fabrication. In Wood Work, it Provides Precise Placement of Screws or Hardware such as Hinges on Wood Grain so that it cannot Pull a Drill Bit Off-Center. With Plastics and Acrylics, Traditional Hammering Methods Could Cause Shattering of these materials; However, the Steady and Localized Pressure applied by the Automatic Punch Provides a Safe Alternative. Due to its Chrome-Vanadium Construction, this Punch can withstand Thousands of Strikes without the Tip Losing Sharpness nor the Internal Spring Losing Tension. The Punch represents a Perfect Blend of Mechanical Simplicity and Professional Grade Performance for any Craftsman.
