The pin vise hand drill, often called a pin vise, is a versatile and compact tool primarily used for drilling tiny holes in soft materials like wood, plastic, and soft metals. While it might seem straightforward to use, there are common mistakes users make that can affect the quality of their work the lifespan of the tool, or even lead to potential injury. This article highlights three of these mistakes and provides tips on how to avoid them.
1. Overforcing the Drill
One of the biggest temptations when using any drill, including a pin vise hand drill, is to apply excessive force to expedite the drilling process. However, doing so with a pin vise can lead to several issues:
a). Breakage of Drill Bits:
The drill bits used in pin vises are typically thin and delicate. Applying too much pressure can easily cause them to snap.
b) Off-center Holes:
Excessive force can cause the drill bit to slip or wander, leading to a hole that isn't precisely where you intended.
c) Work Material Damage:
Overdrilling can cause the surrounding material to splinter, crack, or deform, especially if the material is delicate.
Solution:
Apply steady, gentle pressure when using the pin vise. Let the drill bit's sharpness and spirals do the work rather than forcing it through the material.
2. Using Dull or Damaged Drill Bits
Using dull, damaged, or poorly maintained drill bits can compromise the accuracy and quality of your work. A dull bit requires more force to drill, increasing the risk of mistakes or damage. Moreover, it can lead to ragged or uneven holes.
Solution:
Always inspect your drill bits before use. If they appear dull, sharpen them if you have the means and knowledge or replace them. Given the relatively low cost of pin vise drill bits, keeping a fresh stock on hand is a good practice.
3. Not Securing the Workpiece
A common oversight when using a pin vise hand drill is failing to hold or clamp down the workpiece securely. An unstable or moving workpiece can make it challenging to drill accurately and be a safety hazard.
a) Wandering Drill Bit:
If the workpiece isn't secured, it can move while you're drilling, causing the drill bit to wander and result in inaccurate holes.
b) Potential Injury:
An unsecured workpiece can slip, possibly causing the drill bit to jab into your hand or fingers.
c) Uneven Drilling:
A moving workpiece can lead to holes angled incorrectly or not drilled through the intended depth.
Solution:
Always ensure your workpiece is stable before starting. This can be achieved using clamps, a vise, or a steady hand. If you're working on a slippery surface, consider placing a rubber mat or non-slip pad underneath the material to provide additional stability.
While the pin vise hand drill is a handy tool that can provide precision and control for small-scale projects, it's essential to use it correctly to achieve the best results and ensure safety. By being mindful of these common mistakes and implementing the provided solutions; you can ensure that your pin vise hand drill serves you effectively for years to come. Whether you're a seasoned professional or a hobbyist just getting started, always remember to prioritize quality and safety in your work.
