Yes, these bits are compatible with any standard drill that accepts a 10.5mm shaft size.
The black oxide finish helps reduce friction during drilling and provides better resistance against rust and corrosion.
While these can drill through many metals, stainless steel is very tough; always use a cooling agent and slow speed to avoid damaging the bit.
It is the angle of the cutting tip, which is standard for general-purpose drilling, balancing ease of entry with durability.
This set includes 5 individual 10.5mm drill bits.
No, oil is only recommended for metal applications to reduce heat and friction. Wood drilling should be done dry.
Use a center punch to create a small indentation before starting to provide a seat for the drill tip.
Reduce your drilling speed and apply a cooling agent or cutting oil to dissipate heat.
Ensure the bit is sharp; if dull, the bit may need to be replaced or professionally resharpened.
To ensure the longevity of your Dapetz drill bits, secure them firmly into a compatible 10.5mm or larger drill chuck. Always ensure the bit is seated deeply and tightened securely to prevent slippage. When drilling, align the 118-degree point accurately before engaging the motor to prevent wandering. Post-use care is simple: wipe the bits clean of debris and metal shavings with a dry cloth. If you have used them in humid conditions, consider a light coating of machine oil before storing them in a moisture-free environment to maintain the integrity of the black oxide finish.
