Buying Guide: Subland Drill Bits
📋 Table of Contents
1What material should subland drill bits be made from for drilling metal?
High-speed steel (HSS) works for general metalworking, but carbide-tipped bits last much longer and handle harder materials like stainless steel and cast iron. Cobalt alloy is a good middle ground if you need better heat resistance without the cost of full carbide.
2Why does the subland design matter compared to standard drill bits?
The subland design reduces the outer diameter of the cutting edge while keeping the core strong, which reduces thrust requirements and friction—this gives you better control and cleaner holes, especially in softer metals like aluminum. It's particularly useful if your drill press has limited power or you're working with delicate materials.
3What size range do I actually need for general workshop use?
A starter set covering 1mm to 13mm in 0.5mm increments handles most common jobs, but check your actual project needs first—if you're doing precision work in small components, you might want a finer range; for larger fabrication, you can skip the smallest sizes. Having a few duplicate bits in the sizes you use most (like 3mm, 5mm, and 8mm) saves time waiting for replacements.
4How do I know if a subland drill bit will fit my drill?
Check your drill's chuck capacity (usually marked on the chuck itself) and make sure the bit's shank diameter doesn't exceed it—most workshop drills take up to 13mm or 16mm. Also verify your drill's maximum RPM matches the bit's recommended speed, as subland bits in carbide can require higher speeds than HSS to perform properly.
5When should I buy a quality brand instead of budget bits?
Invest in better bits if you're drilling regularly in hard materials, need tight tolerances, or work with expensive stock—quality bits stay sharp longer and reduce scrap from overheating or wandering holes. Budget bits are fine for occasional DIY work or practice, but they dull quickly and create frustration on precision jobs.
