Drill Bits for Metalwork
Understanding Drill Bit Varieties
The right drill bit is as crucial as the drill, especially in metalwork, where precision and durability are key. Metalworking requires different types of drill bits.
These include twist, step, cobalt, and carbide drills. Designers create each type for specific metals and drilling needs. The drill bit you choose affects drilling ease, hole quality, and the longevity of the bit and drill.
Selecting the Right Drill Bit for the Job
Selecting the right drill bit involves more than matching the size and shape to the hole you need. Considerations include:
- The hardness of the metal.
- The type of drilling (e.g., through-hole or blind hole).
- We require a high finish quality.
Cobalt drill bits are good for tough metals like stainless steel. Carbide drills are valued for being very hard and resistant to heat.
Features and Coatings for Enhanced Performance
Drill bits for metal also come with various coatings and features that enhance their performance. Titanium and black oxide coatings make the bit last longer and drill smoother by reducing friction and increasing durability. The angle of the drill bit tip is important for reducing “walking” and ensuring accurate starts in metal drilling. The 135-degree split point is also important for this purpose.
Selecting the appropriate drill bit is a nuanced decision that significantly influences the outcome of your metalwork project. With the right drill bit, you can achieve clean, precise holes, efficient drilling, and prolong the life of your drill and bits. This section will discuss effective methods for drilling into the metal to achieve optimal results with your tools.
Techniques for Effective Metal Drilling
Marking and Starting the Hole
Before drilling into metal, precise marking and starting are crucial for accuracy. Use a centre punch to create a dimple at the drilling point, which prevents the drill bit from wandering. Start with a small pilot hole, especially in hard metals, to guide the more significant drill bit and ensure precision.
Optimal Drilling Speeds and Feeds
The proper combination of drilling speed and feed rate is essential for effective metal drilling. Slower speeds with steady pressure are ideal for drilling harder metals, preventing overheating and bit wear. Moderate speeds with lighter pressure work best for softer metals, allowing the bit to cut efficiently without binding.
Lubrication and Cooling Techniques
Lubrication plays a vital role in extending the life of the drill bit and ensuring smooth drilling. Use cutting oil or a specialized metal drilling lubricant to reduce friction and heat buildup. Cooling and lubricating periodically are recommended to maintain bit integrity and prevent metal deformation during prolonged drilling sessions.
