1.Long twist drill bits
Long twist drill bits are designed for drilling holes which run deeper than a standard-length drill bit. A typical example might include installing security latches on a door, which would require drilling down through the ends of the workpiece to a depth of up to one foot.
An especially long twist drill bit will be required to complete everyday tasks such as these, but the main potential disadvantage of an extra-long drill bit is that it can tend to wander more as it goes. Longer twist bits are also more prone to breaking at lower gauges than short bits, particularly when more force is applied to get through greater depths of material. Twist drill bits are also available in a short form. HSS-R 4341 Twist Taper Length Drill Bit Black Rolled Polished

2.Reverse twist drill bits
Reverse twist drill bits are designed to work with your drill set to the reverse rotation direction (counter-clockwise). However, unlike a standard drill bit which would simply drag its cutting edge backwards around the interior of the hole with the drill running backwards, reverse twist drill bits are machined with their fluted cutting surfaces facing in the opposite direction. HSS-R HSS 4341 Roll Forged Twist Drill Bits Black&Gold For Metal Plastic
When a reverse bit is inserted into a chuck and the drill is run counter-clockwise, this means that the bit performs the same sort of cutting action that a standard drill bit does when moving clockwise. This can be extremely useful as a method of screw extraction when the slots on a screw head have been worn away.  DIN340 High Speed Steel HSS 4341 Long Type Drill Bits Set
