FAQs
Can I use these bits on concrete or masonry?
No, these are High-Speed Steel (HSS) bits designed for metal and wood. Using them on masonry will dull the edges instantly.
What is the material composition of these bits?
These are professional-grade HSS (High-Speed Steel) bits, designed for heat resistance and durability.
Does the set include a storage index?
Yes, the S09500M41 comes with a dedicated storage case designed for easy size identification and protection.
Should I use lubricant when drilling steel?
Yes, using a cutting fluid or oil will significantly extend the life of the drill bit and improve the finish quality of the hole.
Are these bits compatible with standard hand drills?
Yes, they are fully compatible with any standard drill equipped with a 3-jaw chuck.
Troubleshooting
Bit is getting very hot and smoking
Reduce your drilling speed (RPM) and ensure you are using a quality cutting oil to dissipate heat.
Drill bit is wandering or slipping
Use a center punch to create a small dimple in the material before starting to provide a guide for the tip.
Bit is dull and not cutting effectively
Check if the bit has been damaged by high heat; re-sharpening using a proper bench grinder jig may be necessary.
Pros and Cons
Pros
- Superior heat resistance for heavy-duty drilling
- Precise hole sizing for professional engineering standards
- Well-organized case for quick size identification
- Durable construction ensures a long service life
Cons
- Not suitable for extremely hardened steel or exotic alloys
- Requires manual oiling for best results in metal

Setup, Compatibility & Care
To maximize the life of your Presto HSS bits, always ensure the workpiece is securely clamped to prevent "grabbing" or bit breakage upon breakthrough. These bits are compatible with standard 3-jaw chucks found on most electric and pneumatic drills.
Care instructions include:
- Cleaning: After use, wipe away metal shavings and apply a light coat of machine oil before returning to the storage case to prevent oxidation.
- Speed Selection: Use lower RPMs for larger bit diameters to prevent overheating the steel.
- Storage: Always return bits to their specific slots in the index case to protect the cutting edges from striking each other.
