Frequently Asked Questions

Q: What materials can this titanium-plated countersink drill bit be used on?

A: This countersink drill bit is designed for use on wood, MDF, PVC, acrylic, chipboard, and plastic with a hardness rating below 25 degrees. It is not recommended for hardened metals or materials above that hardness threshold.

Q: What size countersink drill bit should I choose for my project?

A: Four sizes are available: 2–5mm, 5–10mm, 10–15mm, and 15–20mm. Select based on the diameter of the screw or fastener you're countersinking. For most standard woodworking screws, the 5–10mm size is the most commonly used option.

Q: What is the benefit of the titanium-plated coating on this drill bit?

A: The titanium-plated coating significantly increases the bit's wear resistance, reduces friction during drilling, and extends its overall service life compared to uncoated HSS bits. It also gives the bit its distinctive gold color, making it easy to identify in your toolbox.

Q: Does the internal chip removal design really make a difference?

A: Yes — the internal chip removal channel directs debris away from the cutting surface and out of the hole as you drill. This helps prevent debris from flying and keeps your countersink cleaner, resulting in a neater, more precise finish.
