Quality construction you can rely on

These bits use high-speed steel (HSS) with a titanium coating. The coating boosts wear resistance and lowers friction, which can contribute to smoother cuts and longer bit life. The titanium layer also helps chips clear more readily, supporting cleaner results over time.

• HSS core provides strength and stability during cutting
• Titanium coating reduces wear and heat buildup for repeated use

Design, performance, and cooling options

The spiral flute design supports quick chip removal and smooth cutting action, helping you maintain control through each pass. The bits are compatible with several cooling methods, including oil mist, water, oil, and air, allowing you to tailor cooling to your material and drift conditions during the drilling process.

Practical uses and portability

Compact enough to slip into a pocket or toolkit, this set is ideal for DIY projects, professional crafts, and on-the-go work. It pairs well with jewelry making, micro-bead customization, and small-scale resin or wood drilling, offering dependable performance when space and weight matter.

• Portable design supports fieldwork or rapid project adjustments
• Versatile applications across resin, amber, beadwork, and light wood tasks

While results depend on technique and materials, the ARROWMAX Twist Mini set aims to provide precise, repeatable performance with a focus on durability and ease of use in compact formats.
