A self-feed drill bit designed for accurate, uninterrupted drilling in demanding tasks. Carpenters and keen DIYers benefit from re-sharpenable cutters and a shank designed to resist slippage. Is Bosch SF3001 Self-Feed Drill Bit the durable, workshop-ready bit worth keeping on the shelf?
⚡ At a Glance
- • Cutting Quality: Deep cutter gullets and spurs improve chip clearance for steadier cutting action
- • Best for: High-volume drilling tasks where re-sharpenable edges extend service life
- • Not ideal for: Buyers who need to confirm local packaging, labeling or fit for international versions
A 3 in self-feed drill bit with a 7/16 in hex shank for reduced slippage. Chip lifters and spurs are re-sharpenable while deep cutter gullets help maintain smooth drilling.
Reduced slippage, thanks to 7/16 In hex shank
A 7/16 in hex shank locks into the chuck to resist rotation under load, while 3 in and larger sizes use a three-flat shank for extra grip. The firmer engagement lowers the chance of the bit twisting inside the drill.
Steadier, more accurate holes when drilling by hand or under higher torque. Less bit walk gives cleaner starts and reduces wasted material.
Longer usable life, with re-sharpenable chip lifters and spurs
Chip lifters and spurs are designed so cutting edges can be re-sharpened rather than discarded. Restoring the edges returns the original cutting geometry and keeps performance consistent.
Maintains cutting performance over multiple sharpening cycles, delaying replacement. Practical for workshops that prefer maintenance over frequent disposables.
Smoother drilling, with deep cutter gullets
Deep cutter gullets create larger channels for chip evacuation, reducing the chance of clogging and torque spikes that can stall rotation. Efficient chip removal keeps the cutter engaged with material rather than packing out.
Fewer interruptions and more consistent feed speed during long cuts. Better chip handling helps when working through thicker sections.
