10 x Supercraft - 3/8" HSS Drill Bit - Titanium Coated High-Performance Metal Bit (Bundle Pack)
The Supercraft 3/8" HSS Drill Bit is an industrial-grade cutting tool engineered for precision drilling through a wide variety of metals. Manufactured from High-Speed Steel (HSS), this bit is enhanced with a premium Titanium coating, which significantly reduces friction and heat buildup during operation. This advanced coating not only extends the life of the cutting edges by up to three times compared to standard bits but also allows for faster drilling speeds and cleaner holes. Designed with a standard straight shank for compatibility with most manual and electric hand drills, this bit delivers the structural integrity and sharpness required for professional metal fabrication, greenhouse maintenance, and heavy-duty workshop repairs.
Best For: Precision drilling in mild steel, aluminum, brass, and copper, as well as general-purpose use in timber and specialized plastics.
Key Features
- Titanium Nitride Coating: Provides a high-hardness surface that resists heat and friction, ensuring the bit remains sharper for longer and requires less force to penetrate hard materials.
- High-Speed Steel (HSS) Core: Forged from premium HSS for maximum durability and resistance to breakage under the high-torque conditions of metal drilling.
- Universal Hand Drill Compatibility: Engineered for use with standard keyed or keyless chucks, making it a versatile addition to any professional or domestic tool kit.
- Clean & Accurate Boring: Features precision-ground flutes for efficient chip removal, preventing clogging and ensuring a smooth, burr-free finish on the exit hole.
- Industrial-Standard Durability: Specifically designed to withstand repetitive use in demanding fabrication environments without losing its structural temper.

Oversized Item Delivery Options
Since oversized items require special handling, we may need to provide a custom freight quote for your order and will contact you with an updated shipping rate.
Available options include:

Important Note on Availability & Shipping
Our warehouse serves as our office and logistics centre rather than a retail showroom. Because we ship from multiple locations and manage high-turnover stock, not all items are available for immediate pickup.
Lead Times:
- In-Stock Items: Usually ready for dispatch the same day.
- Supplier-Dependent Items: Usually take 2–8 weeks to arrive, depending on supplier availability. Products from Adloheat may take 8–12 weeks to manufacture—they are made to order in Australia by a small business, and longer lead times reflect the care put into quality.
While we strive for fast delivery, some timelines are subject to supplier availability and are beyond our control. We appreciate your patience as we source the best quality gear for your project.
Biosecurity & Interstate Shipping Restrictions
Due to strict state biosecurity regulations, we are unable to ship some products to certain states and territories:
- Potting Mixes cannot be shipped to Western Australia (WA), the Northern Territory (NT), or Tasmania (TAS).
- Seeds cannot be shipped to Western Australia (WA).
Orders placed for these items to restricted states will be cancelled and refunded. It is the customer's responsibility to ensure that the items being ordered can lawfully be delivered to their state or territory.
