An apparatus for securely holding a drill bit for use with a handheld drill, the drill bit including a pointed end and a bottom end, the apparatus comprising:

• a collet including
• a silo for accommodating the drill bit therein, the silo including a fixed stop such that the bottom end of the drill bit rests against the fixed stop;
• and
• a compressible collar for securing the drill bit within the silo when the apparatus is inserted into the handheld drill,
• wherein the drill bit has a drill bit length and the silo has a silo depth shorter than the drill bit length such that, when the drill bit is inserted into the apparatus with the bottom end resting on the fixed stop, the pointed end of the drill bit protrudes from the apparatus by a maximum depth defined by the drill bit length minus the silo depth, and
• wherein the apparatus, when used with the handheld drill, only allows drilling of holes having a depth up to the maximum depth.
