Last week, the London Metal Exchange copper market was slightly tighter due to tight fundamentals. Metal consumers, producers, analysts and traders gathered in London to participate in the LME annual meeting, resulting in few trading seats and at the same time, last Wednesday. The expiration of options (options) also increases uncertainty and volatility. London's three-month copper closed at $3,941/ton on Thursday, up $37 from the end of the previous period.
The Shanghai copper market showed a pattern of slightly lower prices. As the copper price is already in a historically high area, the differences between the long and short positions have been aggravated, and the investors have a strong wait-and-see attitude. Coupled with news that the State Reserve has to sell 3 to 50,000 tons of copper, the Shanghai Stock Exchange stocks have also increased significantly, putting pressure on the market. The main 0601 contract closed at 36,600 yuan/ton last Friday, down 20 yuan from the previous Friday's closing price. A total of 329,810 contracts were sold each week for a total turnover of 60.316 billion yuan.
Last week, the international aluminum market was stronger than the copper futures. Fund buying gradually increased. The increasing demand for aluminum and high oil prices meant that the outlook for aluminum prices was bullish. At the same time, from the fundamentals, there may be some production plants in Europe and North America. It also makes the market stronger. London’s three-month aluminum closed at $2014/ton on Thursday, up $54 from the end of the previous period.
Shanghai Aluminium Market is still within a narrow range, and under the influence of continued production cuts, aluminum supply is likely to decrease. In the current peak season, it is favorable for prices to rise. However, the price of alumina has risen weakly in the short term, making the aluminum price increase limited. The main 0601 contract closed at 17,210 yuan/ton on Friday, up by 70 yuan from the previous Friday's closing price. In the week, the cumulative turnover of contracts reached 42,480 contracts, and the transaction value was 3.639 billion yuan.
Forstner bits, flat-bottomed to drill holes in wood materials, they can cut on the edge of a block of wood, and can cut overlapping holes; for such applications they are normally used in drill presses or lathes rather than in hand-held electric drills. Because of the flat bottom of the hole, they are useful for drilling through veneer already glued to add an inlay.
The bit includes a center point which guides it throughout the cut (and incidentally spoils the otherwise flat bottom of the hole). The cylindrical cutter around the perimeter shears the wood fibers at the edge of the bore, and also helps guide the bit into the material more precisely.
Forstner bits have radial cutting edges to plane off the material at the bottom of the hole. The bits shown in the images have two radial edges; other designs may have more. Forstner bits have no mechanism to clear chips from the hole, and therefore must be pulled out periodically.
