Buyer’s Guide

When it comes to drilling into hardened steel, it’s essential to choose the right drill bits. This buyer’s guide will provide you with important features to consider, factors to take into account, and general advice to help make an informed decision when purchasing drill bits for hardened steel.

Important Features to Consider

Drill Bit Material: Choose drill bits made from high-quality materials like carbide, diamond, or cobalt. These materials are more durable and can withstand the wear and tear caused by drilling into hardened steel. Carbide-tipped drill bits are a popular choice due to their strength and resistance to heat.

Factors to Take into Account

Shank Size: The shank size refers to the diameter of the metal part that connects the drill bit to the drill. It’s crucial to choose the correct shank size for your drill to ensure proper fit and function. Compatibility with your drill is essential for optimal performance. Most drill bits for hardened steel come in common shank sizes like 1/8” and 3/8”.

General Advice for Choosing Drill Bits for Hardened Steel

Know the Hardness of the Steel: Understanding the hardness of the steel you’ll be drilling into is crucial for selecting the right drill bit. Common steel hardness grades vary from Rockwell C2 (soft) to Rockwell C60 (hardened). High-carbon and low-alloy steels generally have a hardness of around Rockwell C30-C40, while high-alloy and stainless steels are usually around Rockwell C50-C60.

Maintenance and Safety Tips

Keep Drill Bits Sharp: To maintain optimal performance, regularly sharpen your drill bits. A dull drill bit can cause uneven holes and increased risk of breaking the bit. Use a high-quality sharpening tool and follow the manufacturer’s recommendations for sharpening your drill bits. 2. Wear Proper Safety Gear: When working with drill bits for hardened steel, always wear appropriate safety gear, including safety goggles and gloves. This will protect you from debris and potential injuries.

Cobalt steel drill bits, on the other hand, offer a balance of toughness and durability, while high-speed steel drill bits exhibit excellent heat resistance and sharp cutting edges, making them an ideal choice for high-speed drilling applications.

What is the difference between drill bits for hardened steel and standard drill bits?

Drill bits for hardened steel are specifically designed to effectively drill through hardened steel surfaces, whereas standard drill bits are intended for drilling through softer materials like wood and plastic. The primary differences between the two types of drill bits are:

Material, 2) Hardness, and 3) Shape.

Drill bits for hardened steel are typically made from hard materials such as carbide, cobalt steel, or high-speed steel, whereas standard drill bits are often made from softer materials like high-carbon steel or alloy steel. The hardness of the material is important because it determines the bit’s ability to withstand the wear and tear of drilling through hardened steel without breaking or losing its sharp edge.

Can I use standard drill bits for drilling through hardened steel?

While it may be tempting to use standard drill bits for drilling through hardened steel, it is generally not recommended due to the significant risk of damaging the bit or cracking the steel surface. Standard drill bits are not specifically designed to handle the extreme force and wear associated with drilling through hardened steel, which can lead to premature failure of the bit and suboptimal drilling results.

Using a drill bit specifically designed for hardened steel will help ensure a smoother, faster, and more efficient drilling process, while minimizing the risk of damage to the bit or the steel surface. Investing in the right drill bit for the job will ultimately save time, effort, and money in the long run.

How do I maintain and sharpen drill bits for hardened steel?

Proper maintenance and sharpening of drill bits for hardened steel is crucial to ensure their longevity and optimal performance. Some key tips for maintaining and sharpening these bits include:

Cleaning and Inspection after Use, 2) Proper Storage, and 3) Sharpening using a Drill Bit Sharpener or Grinder.

After drilling, make sure to thoroughly clean the bit to remove any debris or metal chips that may have accumulated. This step will help prevent the buildup of rust and other contaminants, which can reduce the bit’s effectiveness over time. Additionally, inspect the bit for any signs of wear, such as dulling of the cutting edge or chipping, and address these issues promptly.
