Can I Use HSS Drill Bits in My CNC Router?

Absolutely! Our HSS bits are meant to be used with Drill Adapters, Counterbores and Adjustable Depth Stop Countersinks.

In fact, drilling countersinks with these bits on the CNC machine is a great way to save time and have your pieces look great every time!

With the adjustable depth drill bit you can adjust them for whatever size material you’re working with. They are best used with a drilling toolpath, utilizing the peck drill option at 0.25” per pass with a 0.125” retract height.

For best results, run at 3,000 RPM with a 30 Inches Per Minute (IPM) plunge rate. No feed rate needs to be set with these as they only move up and down with the Z axis, not side to side. If your software doesn’t allow a 0 feed rate, you can enter 1 IPM in the feed rate as a placeholder.

How to Choose the Right High-Speed Drill Bit for Your Project?

Check the Flute Design

Evaluating the flute design of a HSS drill bit is crucial for ensuring smooth operation and a seamless drilling experience that enhances overall efficiency.

The different designs to cater to specific drilling needs, including the "HSS Twist" type, regular flute, and slow spiral designs. Each of these designs has characteristics that make them suitable for different applications:

HSS Twist Drill Bits:

  • The twist drill bit is the most common type of drill bit for metalworking. The term "twist" refers to the spiral (helix) angle of the flutes, which are the grooves or channels wound around the body of the drill bit.
  • Twist drill bits are designed to provide a good balance between durability and cutting speed, making them suitable for a wide range of materials and applications.
  • The helix angle of a standard twist drill bit is usually around 30 to 40 degrees, which is considered a "normal" or "regular" helix angle.

Regular Flute Drill Bits:

  • Regular flute drill bits can also be twist drill bits, but the term "regular flute" emphasizes the design of the flutes rather than the spiral angle.
  • These drill bits are designed for general-purpose drilling in most materials, including metal, wood, and plastic.
  • The flutes are designed to efficiently remove chips and debris from the hole, keeping the drill bit cool and reducing wear.

Slow Spiral (Low Helix) Drill Bits:

  • Slow spiral drill bits have a smaller helix angle, typically less than 30 degrees. This design is also referred to as a "low helix" drill bit.
  • The slow or low helix angle makes these bits more efficient at cutting hard, abrasive materials such as stainless steel or titanium. The slower spiral helps to reduce the buildup of heat and improves chip removal, which is critical in hard materials.
  • They are particularly useful for applications requiring a high degree of control and precision, as the slower spiral rate reduces the tendency of the bit to "walk" or wander at the start of drilling.

The main difference between these types of HSS drill bits lies in their flute design and helix angle, which affects their cutting performance, chip removal, heat generation, and suitability for different materials. "HSS Twist" generally refers to the common, versatile design, "regular flute" emphasizes the chip removal capability, and "slow spiral" or "low helix" bits are tailored for hard materials where control and reduced heat are paramount.

Consider the Shank Size

Considering the shank type of a HSS drill bit is important to ensure compatibility and enhanced control during drilling operations for superior results.

If you are using an HSS bit in a CNC router, then, for 5/16" dia. round shank use a 7-8mm Spring Collet. (A spring collet is a holding device designed to reduce the vibrations on the tools and motors, assure better results and prolong the life of the tools and electrospindles.) For 3/8" dia. round shank use 9-10mm Spring Collet.

What Are Some Tips for Using High-Speed Drill Bits Safely?

Utilizing HSS drill bits safely involves following essential tips such as leveraging safety features and ensuring user-friendly practices to maintain a secure and effective drilling environment.

  1. It is crucial to carefully read and understand the user manual accompanying the drill bits to familiarize oneself with the specific features and operational instructions.

  2. Before starting any drilling work, always wear appropriate safety gear such as goggles to protect your eyes and gloves to shield your hands.

  3. It's vital to inspect the drill bits regularly for any wear or damage and replace them as needed to prevent accidents or damage to the workpiece.

By incorporating these safety measures into your drilling routine, you can ensure a safe and successful drilling experience.

What Are Some Common Mistakes to Avoid When Using High-Speed Drill Bits?

Avoiding common mistakes when using these drill bits is crucial for maintaining improved accuracy, enhanced control, and overall safety during drilling operations.

  1. One common mistake to avoid is applying too much pressure when drilling. Many individuals tend to push too hard, which can lead to overheating the drill bit, causing it to dull quickly and result in imprecise drilling.
  2. Failing to secure your workpiece properly can lead to dangerous kickbacks or the workpiece spinning out of control. Another important consideration is using the correct speed setting for the material being drilled to prevent overheating and potential damage.

Always wear proper safety gear, such as goggles and gloves, to protect yourself from flying debris and potential injuries.
