Product Information
Full details
The Sealey HSS Drill Bit Set (DBS25RF) is a versatile 25-piece collection of general-purpose drill bits, ideal for hobbyists, woodworkers, and DIY enthusiasts who need reliable bits for light-duty metal and wood tasks. These bits are manufactured to DIN 338 standards for consistency, though users should note that as roll-forged high-speed steel bits, they are optimized for general use rather than heavy-duty industrial hardened steel applications.

Extended Product Information
FAQs
Can I use these bits on stainless steel?
These bits are HSS and will work on mild steel, but they are not specifically hardened for thick stainless steel; if you must use them, use very slow speeds and plenty of cooling fluid.
What is the smallest and largest size in the set?
The set ranges from 1mm up to 13mm in 0.5mm increments.
Are these bits cobalt-tipped?
No, these are standard roll-forged HSS bits manufactured to DIN 338 standards.
Does the set come with a case?
Yes, it includes a robust, indexed storage case that keeps the bits organized by size.
Can these bits be used in a cordless hand drill?
Yes, they are designed to be compatible with both standard handheld drills and bench pillar drills.
Troubleshooting
Bit wandering on the material surface
Ensure a center punch mark is used or start with a much smaller pilot bit to guide the larger bit.
Bit overheating or smoking
Reduce your drilling speed and apply cutting fluid to lower friction and assist with heat dissipation.
Hole diameter is slightly irregular
Check that the bit is fully centered in the chuck and ensure the drill is being held at a perfect 90-degree angle to the surface.
Pros and Cons
Pros
- Comprehensive size range in 0.5mm increments
- Clear, logical indexing in the included storage case
- Suitable for a wide variety of materials including wood and light metal
- Standardized tip geometry for predictable results
Cons
- Roll forged construction is not intended for hardened, heavy-duty steel
- Standard HSS may blunt faster than cobalt-infused bits when drilling stainless steel
- Small drill bits (under 2mm) are naturally fragile and require high precision handling
Setup, Compatibility & Care
To ensure the longevity of your drill bits, follow these maintenance practices:
- Storage: Always return each bit to its designated slot in the case after use to prevent edge dulling caused by metal-on-metal contact.
- Speed Selection: Use higher speeds for smaller bits and lower speeds for larger bits to prevent snapping or burning.
- Lubrication: When working with metals, use a light oil or cutting fluid to reduce friction and heat buildup.
- Compatibility: Ensure the chuck on your drill is clean and tightened correctly to prevent slipping or bit damage.
- Cleaning: Wipe bits down with an oily rag after use, especially if they have been exposed to moisture, to prevent surface corrosion.
