How do self centering drill bits work?
A self-centering drill bit has a tapered nose that will be automatically centered when placed in a tapered hole, such as a hinge. Because of this, they ensure that all the holes are straight, aligned, and just the right depth.
How can I drill straight without a drill press?
Using glue and clamps, place the blocks against a square to ensure a perfect 90° angle. Allow the glue to dry, then drill a hole in one side and add some string or wire for easy storage. I keep mine attached to a clip on my tool bag, where I keep my drill, some bits, a small level and drywall anchors for small tasks.
What is a drill guide?

How do you drill long straight holes in metal?
Drill at a Slow Speed
In general, it’s a good idea to drill through metal using as slow a speed as possible using a drill bit for metal. Hard metals like steel and larger drill bits require even slower speeds. With a small twist bit (1/16 in. to 3/16 in.), you can drill through most metals at 3,000 rpm.
How do you turn a shaft without a lathe?

What is drill rod?
What is drill rod used for? Drill rod is unhardened, precision ground, round bar used in a variety of industries including manufacturing and construction. It is often used in the manufacture of dies, punches, drills, gauges, pins, and other machine parts that require high strength and durability.
What grade of steel is drill rod?
AISI A2 Tool Steel Drill Rod is an air-hardening tool steel that contains five percent (5%) chromium. The chromium in drill rod replaces the oil hardening (O1 type). A2 Drill Rod is ideal for applications where safer hardening, less distortion and increased wear-resistance are required.
What is square bar?
Square Bar is a solid metal bar that has a square cross section. These bars are widely used in many industries for general assembly or manufacturing. They are also used for general repairs of plant equipment and railings. Common applications include ornamental iron work, gates and protective barriers on windows.

How strong is round bar?
It contains a minimum of 12 per cent chromium, just sufficient to give corrosion resistance properties. It has good ductility in the annealed condition but is capable of being hardened up to Rockwell Hardness 50HRC, the highest hardness of the 12 per cent chromium grades.
What is shafting steel?
Shafting, also known as ‘Turned Ground and Polished’ shafting, refers to round bars made with fine precision and high-quality steel. They are polished to ensure flawless and perfectly straight surfaces.
What is shaft rod?
Shaft: A shaft is a metallic, rotating and oscillating rod that rotates continually to transfer movements or torque in the machine. Shaft is usually used to connect other components of machine that cannot be connected due to distance between them and to allow relative motion between them.
What is rods metal?
Metal rods are metals and alloys designed in the pattern of round bars or rod, rectangular or flat bars, square bars, hexagons, and other patterns of bar stock. These shapes also come in billet form and generally include a cross-section based on the shape of rod or bar stock.
